US Consumer

Reading Time: < 1 minute

Or American consumers. I did not realized that the consumer credit card debt skyrocketed recently until I saw a year at Twitter. This chart has about 4 years of data: both the credit card loan and personal savings. The source of data is from FRED (I think it stands for Fed Research Economic Data): I noticed this link is actually from St. Louis fed, not too far from where I live. This chart has about 20 years worth of data. Besides the long term overall trends: consumer debt goes up in last 20 years in general, savings rate were mostly flat except the two stimulus rounds during 2020 / 2021 pandemic. But from Mar 17, 2021, it seems the two curves went totally opposite directions, the debt went up, the savings went down.

This is not sustainable, if we use some common sense. Because the consumers will accumulate debt, a similar analogy is the US as a country owe money to foreign government in the form of treasury (or debt in the US dollar). This is bad too, because as we may know, the interest on those debt will go up and soon or later the US will hit the debt ceiling (a bit like consumer’ credit card limit).

The US has a lot of smart people, a decent political system, and market based economy. But the “shop until drop” mindset, and / or the over reliance on consumer spending is the achilles heel of the US economy.

Last but not least, “Why Americans Are Drowning In Debt” by CNBC (via YouTube).

Twitter

Reading Time: 2 minutes

I joined Twitter back in March 2008, and it’s been 14 years since I joined it. I don’t remember the exact reason I joined it, but I think one reason is probably in the early days of iOS (iPhone) app development, many developers are on Twitter as well. In recent years, the platform has expanded beyond techies, and into politics, entertainment, breaking news etc. The breaking news feature of Twitter has been there for a while, in my opinion. We can find important news on election, on both domestic and international affairs such as war, and so on. Twitter itself grew quite a bit over last 14 years too. I still remember in its early days, it’s quite often to see the whale picture when the system was down. I vaguely recall when they started they used Ruby (Ruby on rails) a web technology was popular or getting traction then, and slowly changed to something more comprehensive or complicated.

For me personally I probably switched my interest there too, in last few years, I am mostly interested in FinTweets (financial or stock related tweets). I tried to stay away from politics, and it was not always successful.

Compared to other platform such as Facebook and LinkedIn, I think I am more open minded, or sometimes blunt, one reason is probably I don’t know a lot of people in person, another reason is probably the culture of Twitter itself is more open. Note Tweets by default is available to everyone in the world (something newbies on twitter sometimes did not realize).

The business of Twitter obviously was not doing well over its 10 years of public market presence, until Elon took it over recently. Elon may even has some of his points: on people’s desire to work or not work, and blue verified could help clean up the public / digital town square. Interesting to learn some of his other thoughts such as easy / smooth jazz mode, vs heavy metal mode (combat mode?), and also his X.com grand plan 22 years ago. This is a recent interview of Elon btw.

Back to Elon’s idea (or ideal) of public / digital town square. This reminded me of something. Note I grew up in China and free speech (like the 1st amendment in the US constitution) was not emphasized. But in 1980s when I was in high school there was still a lot room for feedback or open communication. So once the students in my class put up a feedback notebook, and things quickly went off rails (imagine the early days of the BBS or discussion forum, and then put high school kids to it). Good intention alone sometimes is not enough. I guess similar can be said about Elon’s dream about full automatous driving (self driving), as well as the robots that do all of our work (in addition to chores).

Alternatives to Facebook, LinkedIn and Twitter

Reading Time: < 1 minute

The three legacy social networks 🙂

I have been using the 3 for a while, since 2008 to be precise. I started using LinkedIn after I switched job in Nov 2008 (amid financial crisis), because I realized I want to look for a developer job quickly after I jumped ship. I cannot remember the reasons I joined Facebook and Twitter. But both companies are under tremendous pressure nowadays, and both have lots of issues in terms of “doom scrolling” as well as their business model: the longevity of companies. For Twitter, bought by the worst richest person Elon Musk could have many implications as he was very much unpredictable. Facebook’s Mark Zuckerberg is in full control of the company (Meta) and there were lots of controversies in recent years as well.

I think some people probably just live on FB, LinkedIn or Twitter. I don’t use much the newer and cooler social media such as TikTok, instagram or Snapchat. I may be too old for these. In addition to this blog, I am explorring the following, both on written and video contents:

  1. Medium
  2. YouTube (video and community). YouTube has a feature of custom handle: I still need to think about it (major1xu or oliveCapital)
  3. Substack (noticed Substack has some relationship with Twitter).

PS: I am thinking minimize the use of WeChat too, and use LINE instead.

Rain, umbrella and persuade preteen wear jacket

Reading Time: 2 minutes

Seven years ago, when my 12 year old was 5, and we sent her to a summer camp. One day she came back in the afternoon with wet clothes, and we were upset and I sent angry email to the camp lead counselor (adult who is in charge). At the beginning of last school year (fall 2021), at the middle school, they had similar incident, in which kids wait in the rain for the bus, I recall there was a heated discussion thread on the FB private group (on Ladue Community Connect: more precisely the Aug 26, 2021 post). When I grew up I was taught in a culture to avoid rained on, and more importantly don’t wear the wet clothes for an extended period of time, as it will be bad for one’s health. On the other hand, until recently I started to appreciate that got rained on is not necessary bad. Something like described in this tweet.

Yesterday morning, it rained, and we told our 12 year old to bring umbrella. She was reluctant, and later told me she doesn’t know how to open and close umbrella. I let her practice a few times. She took it.

Dressing warm or put on jacket is more a struggle. Sometimes I was successful, other times I decided it’s not the fight I wanted to pick that day. Like this morning. It was about 40 degrees fahrenheit, and she was the only kid with a T-shirt. She probably put her jacket in the backpack. I waved to her, and did not ask her to put it on. I wish her well today. Hope she doesn’t get cold (I heard getting cold is not necessarily from lack of clothes 🙂

PS: I posted it on Facebook, LinkedIn and Twitter. With a hashtag #preteen (daily struggle etc). And I got warning from the Twitter: “We put a warning on one or more recent Tweets because they might have sensitive content. If you think this warning is a mistake, you can appeal.” || I deleted the tweet.

My cars over the years

Reading Time: 4 minutes

(Update 11-08-2025) 美国二手丰田太贵啦!日系SUV车价/市场/行情/TOYOTA/车市 RAV4/4Runner/Highlander/Grand Highlander/CH-R

(Original) No I don’t drive the Rivian but I drive the Toyota Sienna next to it: owned it for 9 years now (since summer 2013). It was the main car (minivan) I drove in last 9 years, with the exception of sometimes I drove my wife’s Camry for the purpose of saving gasoline, or taking care of maintenance issue.


Recently I also bought a certified pre owned Toyota Camry for my wife as I totaled her older Camry during an accident (I was not hurt).


The clear water blue 2012 Camry was the one we had for 10 years: we owned her from new. Serenity (when she was 2 years old) liked the color. The girls (my wife and 2 daughters) liked her very much too, at the day before the car was towed away, I told my girls to take some pictures. And they did. I was hoping Serenity can learn to drive on the 2012 blue Camry, but sometimes things unpredictable do happen, and the accident was not the worst as I was fine (I was the only person in the car). I think she will likely learn to drive on the white (ice cap) 2020 Camry, or if she likes, hopefully I can get her whatever cool car / SUV she wants when she is 16 (or 15 and a half 🙂

Again we all liked blue Camry very much, especially my wife. It was my wife’s main car, and since she preferred Camry, I got her replacement Camry in a week. The only complaint she had so far is the noise during initial acceleration, which from google it seems quite normal. Camry was known for its quietness, btw. Both Camry and Sienna were fairly reliable. I make sure fixing necessary wear and tear, things such as oil change, tire, wiper blades, breaks and battery. And some other occasional breakages: for Sienna, one recent example is the drive shaft.

Before those 2012 Toyotas, I owned Nissan Altima 2001 (from new) and Subaru Forester 2006 (bought used from Craigslist, in 2010). I regret bought the Altima, at the time I liked its leather and lower price tag compared to Camry. But it’s also a bit smaller than Camry, and it has more maintenance issues in the later years, also the resell value was not as great. Below is the email I sent to the owner of Subaru back in 2010 when I was trying to buy it:

Hi, there,
 
I saw the Ad at St. Louis Craigslist, I would like to know whether the vehicle is still available, and if yes, when is a good time to take a look?
 
http://stlouis.craigslist.org/cto/1854914704.html (this link is no longer available, btw)
 
BTW, from the picture, it is a stick-shift (manual transmission), correct?
 
Thanks,…

========

In Summer 2013 I traded in the Subaru for the Sienna I mentioned above. I recall I did not lose money from it, because like Toyota, Subaru also holds value pretty well.

Old Cars

Before those two, when I was in graduate school in Rolla and was new to the USA, I drove a 1991 Toyota Corolla manual (stick shift). And before Corolla (about $3,000, bought in 1998 or 1999), my first car was black 1984 Toyota Celica 1984 ($450, paid in 1998, also stick shift). I learned how to drive on the Celica in early 1998. I got pulled over by police a few times due to various reasons, one occasion was I could not stay on the lane very well, it was probably in the middle of night, I drove from Rolla Walmart to my fraternity. Now I think about it, if I had the 2020 Camry LDA feature (lane departure alerts, YouTube video – How does Toyota’s Lane Departure Alert With Steering Assist work?), this won’t happen.

EV next?

I think my next car could be either a hybrid or an EV (Rivian hopefully :-). Joking. I think in general, if money or the gasoline is not an issue, one should get a car or a SUV (a truck) as safe as possible. That’s another reason I bought Camry, not only it her the most popular car (sedan) in the USA for many years, it’s also one of the safest: if you could ignore all the white noises in which the US government haul in the CEO / Grandson of Toyota founder, it’s only for the show (for the consumption of some ignorant US TV viewers or let’s just say some Americans. Some people in my humble opinion, should not be allowed to drive: this was the consensus I had with a few graduates at the fraternity when I was in Rolla. Sorry sometimes I have to be blunt. Especially if you consider I was hit by someone from behind recently in a traffic light intersection. Btw, it’s the 2nd time I was hit in an intersection. The first time, the other driver fled, unfortunately. I was able to do some freelance detective work myself, and unfortunately squared, the other driver had no insurance 🙁

Last but not least, I shared some of my recent car shopping experience here:

My Zhenhai Middle School Days我在镇海中学的日子

Reading Time: 6 minutes

Our old daughter Serenity is entering 7th grade this school year, as I said somewhere else, in 6 years she will very likely attend college. Use her word, “I want to a quality college such as Columbia U”. I know she wanted to be a wildlife biologist and last I checked she has no intention to be a engineer or a computer scientist (like her proud dad 🙂 我们的大女儿 Serenity 本学年要上 7 年级,正如我在其他地方所说的,6 年后她很可能会上大学。用她的话,“我想要一所高质量的大学,比如哥伦比亚大学”。我知道她想成为一名野生动物生物学家,最后我检查她无意成为一名工程师或计算机科学家(就像她骄傲的父亲一样)(Chinese is done via Google translate)

The middle school seems getting more serious here. Because Serenity has a few extra curriculum activities in addition to her school, some days she will complain about the work: the homework and the burden comes with it. Plus she is in adolescent age now, let’s just say in some days (or evenings) she was not happy (mostly with herself, sometimes with us). 中学似乎在这里变得更加严肃。因为 Serenity 在学校之外还有一些额外的课程活动,所以有时她会抱怨工作:家庭作业和负担随之而来。再加上她现在正处于青春期,让我们说在某些日子(或晚上)她不开心(主要是对自己,有时是对我们)。

This reminded me my Zhenhai middle school 镇海中学 days. I had a rough ramp up period in my middle school due to two reasons, I think. Note in China middle school is really both middle school and high school in the USA. Zhenhai is a selected school (or magnet school, if I can use an analogy here). As a 5th grade kid, I never imagined I would end up at Zhenhai Middle back in 1983. In fact, even after I passed the test, and academically eligible, because I was only 12 years old, and need to attend this boarding school (there is some financial burden to my parents, unfortunately not trivia for them at the time). After some consulting with my uncle (my mom’s big brother), my parents decided to send me there. One reason is as the old saying goes, entering Zhanhai Middle means one would have “one leg already get into college”. Note going to college is a big thing for us, because at the time, there were really no other good choices other than that. At least not for us (myself, and my two elder brothers). 这让我想起了我在镇海中学镇海中学的日子。我认为,由于两个原因,我在中学经历了一段艰难的成长期。请注意,中国的中学实际上是美国的中学和高中。镇海是一所精选学校(或磁铁学校,如果我可以在这里打个比方的话)。作为一个五年级的孩子,我从没想过我会在1983年最终进入镇海中学。事实上,即使我通过了考试,并且有学术资格,因为我只有12岁,需要上这所寄宿学校(我的父母有一些经济负担,不幸的是当时对他们来说不是琐事)。在与我叔叔(我妈妈的大哥)商量后,我的父母决定送我去那里。原因之一,就是那句老话,进了湛海中学,就意味着“一条腿已经考上了大学”。注意上大学对我们来说是一件大事,因为在当时,除此之外真的没有其他好的选择。至少对我们(我自己和我的两个哥哥)来说不是。

Back to my rough ramp up period. The first reason is easy, I never left my parents or my family for that long before that, I did stay with my paternal grandma for a night during school year, or I stayed at my uncle’s home with my maternal grandma for a few weeks. I was fairly close to both grandparents. At Zhenhai Middle though, I came back home usually once a month, mainly due to the transportation cost. My big brother was attending to the same school when I was in grade 6 (he was at high school), but for some reason I don’t want to delve into, I was not close to my big brother. That situation changed when my 2nd brother joined when I attending the 7th grade. But in my 1st year I was on my own, in terms of washing my own clothes (think the cold water from faucet in winter). The second reason is there were many other talented kids, and there was intense competition mainly on academics. Related to that, my class got a very well known counselor and he was pretty strict too. He is unconventional in some ways, for example, he was math teacher, but he rarely gives lecture. He gave us a lot of homework instead, basically we learned ourselves through doing those homework. We joked the homework is never ending. Because as soon as we finish some, he would give out new ones 🙁 I recall some kids really struggled because they are not used to the pace, the work and I am guessing due to lack of instructions. I am not saying the teacher is all bad. Maybe he was not the best teacher for some of the kids. For me I think I learned self-study in his system. Also, once when I was fairly new, I got sick (fever). He took me to hospital and made sure I was treated. So in a way he was a father figure. He was strict too, as once I got fight into another boy, he gave both of us a hard lesson. 回到我粗略的加速期。第一个原因很简单,在那之前我从来没有离开过父母或家人那么久,我确实在学年期间和我的外祖母住了一个晚上,或者我在我的叔叔家和外祖母住了几个星期。我和祖父母都很亲近。不过在镇海中,我一般是一个月回一次家,主要是交通费。我六年级的时候我哥哥在同一所学校上学(他在读高中),但出于某种我不想深入研究的原因,我和我哥哥关系并不好。当我上 7 年级时,当我的二哥加入时,这种情况发生了变化。但在我的第一年,我自己洗衣服(想想冬天水龙头里的冷水)。第二个原因是有很多其他有才华的孩子,而且主要是在学术上的激烈竞争。与此相关的是,我班有一位非常有名的辅导员,他也很严格。他在某些方面非常规,例如,他是数学老师,但他很少讲课。他给了我们很多功课,基本上我们都是通过做功课来学习的。我们开玩笑说作业永无止境。因为一旦我们完成一些,他就会给出新的:-(我记得有些孩子真的很挣扎,因为他们不习惯节奏,工作,我猜是由于缺乏指导。我不是说老师都不好。也许他不是一些孩子最好的老师。对我来说,我认为我在他的系统中学会了自学。另外,当我还很新的时候,我生病了(发烧)。他带我去医院,并确保我得到治疗。所以在某种程度上他是一个父亲形象。他也很严厉,因为一旦我和另一个男孩打架,他给我们俩上了一课。

In the early days of the 6th grade, I recall once I came home, again the once a month trip, I believe at that time it’s 6 days a week school, so we left school at Saturday afternoon, and back to school on Sunday afternoon. And I brought homework to work on too, again the “never ending homework” from the teacher. I cried because of the burden of the homework. My father asked if I wanted to go back to Zhenhai. Obvious I could not quit. I can think of two benefits of doing the middle school there: 1) I learned self study; 2) I gained confidence among my peers, again note some of the kids are quite smart. I think the latter helped me in high school too. Since I built good foundations in middle school, I did not really worked during high school, and was still able to do decently well. A common slogan the teacher says often is 先苦后甜 or “no pain no gain” in English. 记得六年级初期,有一次回家,又是一个月一次的旅行,我相信当时是一周六天的学校,所以我们周六下午放学,周日下午回学校.我也带了作业去做,又是老师的“永无止境的作业”。因为作业的负担,我哭了。父亲问我要不要回镇海。显然我不能放弃。我可以想到在那里读中学的两个好处:1)我学会了自学; 2)我在同龄人中获得了信心,再次注意到有些孩子很聪明。我认为后者在高中时也帮助了我。由于我在中学打下了良好的基础,所以在高中的时候我并没有真正工作过,而且还能够做得很好。老师经常说的一个常见口号是英语中的“先苦后甜”或“没有痛苦就没有收获”。

Downside of this approach

Again I think for me personally I benefits from this system for the most part. But this is not for everyone. I recall for my cohorts from 白峰中心小学 (Baifeng elementary school),2 boys and 2 girls were admitted to Zhenhai Middle, 3 attended (the other girl actually joined in high school because she is really good / smart), my other 2 friends did not got admitted to the high school at Zhenhai. I also recall a fairly smart girl, who is not particularly good looking (I understand this may not be politically correct, but I am just stating something from my memory), at one time was constantly bashed by the counselor teacher: his approach did not work. I vaguely recall we lost a boy from Hepatitis A in one year (I don’t think the school has a lot of responsibility on this though). I do recall there is some cronyism as well. For example, each class in the middle school has 5 quotas for the kids directly go to high school (no test score requirement), and I don’t think it’s a fair / transparency process. Last but not least, some of the city 城关镇 kids were singled out because they did not do homework, or just lag behind on academics. I was able to dine with some of the old classmates in year 2013 (we graduated from middle school in 1986, high school in 1989), one funny story told by one of the city 城关镇 kid: once he was walking with his mother in law and kid on the street, and the teacher said them, and made a comment “你这样的人也会结婚啊?“ (his implied meaning, a fall-behind student such as you don’t deserve a love from someone and get married). This is obviously not right. Another time, when we were all new to high school, and the teacher threw out my roommate’s luggage out of window due to some discipline issue: I vaguely recall my roommate got overly excited as the next day is winter break. 我再次认为,就我个人而言,我在很大程度上受益于这个系统。但这并不适合所有人。回想起白峰小学中心(白峰小学)的同学,2男2女考入镇海中学,3人就读(另外一个女孩真的上高中,因为她真的很好/聪明),我的另外2个朋友没有考上镇海中学。我还记得一个还算聪明的女孩子,长得不是特别好看(我理解这可能不是政治正确,但我只是凭记忆说一点),有一次经常被辅导老师痛骂:他的做法并没有工作。我隐约记得我们在一年内失去了一个患甲型肝炎的男孩(但我认为学校对此没有太大责任)。我记得也有一些裙带关系。例如,中学每个班级有 5 个直接上高中的名额(没有考试成绩要求),我不认为这是一个公平/透明的过程。最后但并非最不重要的一点是,城关镇的一些孩子因为没有做功课,或者只是学业落后而被单独挑出来。 2013年和一些老同学一起吃饭(1986年中学毕业,1989年高中毕业),城关镇的一个孩子讲了一个有趣的故事:有一次他和妈妈一起在法律和孩子在街上,老师说他们,并且评论“你这样的人也结婚啊?”结婚)。这显然是不对的。还有一次,当我们都是初中生的时候,老师因为纪律问题把我室友的行李扔到窗外:我隐约记得我的室友太兴奋了那天是寒假。

Other hits and misses (or just random facts) in my middle school:

1) I recall we (boys) played quite a bit co-ed basketballs with the girls in the class, that’s until the 2nd or 3rd year, when they girls started their adolescents years (starting period etc.), and they have their separate PE (physical education) class. Some of the girls are very good academically. And I still don’t understand why the St. Louis based private school such as MICDs separate boys and girls on STEMs in middle school (that’s what I heard). 2) I like running but I was not very good at it. So in the 800 meter race, I would use all the energy in the first 200 or 300 meters, then lag behind. 3) I was able to join the computer club and worked on very simple BASIC programming language (a few lines, go to statement etc), and it seems today’s MicroBit and Arduino programming are similar. 4) I could not fall asleep during the ZhongKao (中考) : it’s the admission test from middle school to high school. I recall 2 of my dorm mates were very nice, and tried to help me fall asleep. I think one reason is I knew I had to be successful (and the pressure came with it). Three years later, I had similar issues during GaoKao 高考(college admission exam). Note in China, middle school is 3 years, and high school is also 3 years. 5) We worked at a farm couple times, again because of our counselor (the strict teacher). I think most kids hated it. Because we dealt with cow manure. On the other hand, it was a bit funny for me to explain how rice was grown to a city kid. 6) Talking about city kid, note half of the kids live at home, they are from 镇海城关镇,the other half live in the dorm. The boys were able to live in the newly built dormitory building in 1983, the girls new dorm was built a few years later. I think there are stories on the old dorm too. We did not have hot water for shower. At one time, when we were in high school, we borrowed teacher’s shower room key (it was cold water shower, but still works in summer). 1)我记得我们(男孩)和班上的女孩打了相当多的男女混合篮球,直到第二年或第三年,当他们女孩开始青春期(开始期等)时,他们有自己的独立PE(体育)课。一些女孩的学习成绩非常好。而且我仍然不明白为什么像MICD这样的圣路易斯私立学校在中学的STEM上将男孩和女孩分开(这就是我所听到的)。 2) 我喜欢跑步,但我不太擅长。所以在800米比赛中,我会在前200米或300米用完所有的能量,然后就落后了。 3)我能够加入计算机俱乐部并从事非常简单的 BASIC 编程语言(几行,go to 语句等),看起来今天的 MicroBit 和 Arduino 编程很相似。 4) 中考(中考)睡不着:这是从初中到高中的入学考试。我记得我的两个舍友都很好,并试图帮助我入睡。我认为原因之一是我知道我必须成功(压力随之而来)。三年后,我在高考高考(高考)时也遇到了类似的问题。注意在中国,初中是3年,高中也是3年。 5)我们在农场工作了几次,也是因为我们的辅导员(严格的老师)。我想大多数孩子都讨厌它。因为我们处理的是牛粪。另一方面,对我来说,向一个城市孩子解释水稻是如何种植的有点有趣。 6)说到城里的孩子,注意一半的孩子住在家里,他们来自镇海城关镇,另一半住在宿舍。 1983年,男生得以住进新建的宿舍楼,女生的新宿舍是几年后建成的。我想旧宿舍也有故事。我们没有热水淋浴。有一次,我们上高中的时候,借了老师的淋浴房钥匙(是冷水淋浴,但夏天还能用)。

Best way to track my kids on school buses

Reading Time: 2 minutes

(Update 09-01-2023) I looked around and it seems another app was not not working (it seems the app is called My Ride 360, I never used it btw). It seems “Here Comes the Bus” is more widely used and thinking maybe worth to explore more with them (Android app, iOS app).

(This was written last year 2022) We live in a relatively safe area, and both our school districts and our bus drivers are solid (knock on woods on this one though, as nobody can really avoid accidents or incidents). In the past few years, we (at least I) mostly rely on the mobile app SafeStopApp that tracks the school bus for morning pickup and afternoon drop off. The app is not perfect, as you can see from the customer reviews for android (google play) and iOS (Apple). You may notice I put a nice word for their iOS app, it’s mostly for encouragement purpose 🙂

This school year, I also got a new tool: the Apple airtag. I found airtag very helpful, as it can anonymous talk to nearby cellular / wifi devices and its location is usually updated frequently. Both my girls have an AirTag with them.

I also found another kid in the neighborhood has an apple watch, and talked to parents after getting off the bus, this is very cool. I used to give iPhone to my old daughter, but smartphone could be too much distraction for the kids. So Apple Watch (with cellular) is a good compromise in this sense. Actually I offered my old daughter and asked if she wants one, and she said No so far (I offered credit card to her too, and she politely declined as well). The offer is still on the table.

I wrote this post after I read the story below.

Restarting Math Fact Scholars

Reading Time: 4 minutes

(Update 11-16-2023) I created a MFS FAQ blog post today: I used some of the content below, plus some of the common questions being asked in last year or so. In the future, I will try to maintain/update that one.

(Update 11-02-2023)

A few parents asked about the “1st test” PDF file. It’s the first test a kid will start taking in a particular Tuesday morning (this is just for reference). Each kid is different, so no need to compare your kid with her/his friend. That being said, I believe practice on workbooks is equally important, if not more, compared to the “timed tests” we do on Tuesday mornings. Last but not least, a kid doesn’t have to come every Tuesday morning for testing sessions. Please bring the kid when it works for you/your family and when the kid is ready.

Btw, here is web order form (you will need the SSA MTK credentials to log in).

(Update 09-07-2023)

I just realized today that a couple families re-ordered the same workbooks, and I assume it’s not their intention to reorder (I will re-confirm with each on an individual basis). || Please don’t reorder the same workbooks.

We (the kids) pick up where they left off. For example, last school year, a kid ends up Gold +10, he/she will start from Gold +11. We are not going back. If the kids have the workbooks (in most cases I believe it’s the case), he/she continues to work on it.

The only reason I can think of why you may want to order the same workbooks, is, for example, you lost the workbooks for some reason and / or really wanted the kids to have more practice.

If in doubt, email or text me before placing the order.

(Original 09-2022)

The ordering form is here: the main difference from earlier is now we offer packages only. At least from the Membership Toolkit (MTK) website at this time. Note you will need to register at this MTK website in order to see the form. For some parents I think they may already have the workbooks, or they need workbooks that are not 100% same with the package, please let us know (email: spoedemathfactscholars@gmail.com; text 314 540 2721), and we will try to work out something. After ordering, the workbooks will arrive in about a week. My current thinking is have the teacher giving it to the kid: but we can discuss delivery (in the Spoede school boundary) or pickup as needed too.

Also, if you prefer pay via check / cash, or if you need to register your kids outside of those pre-defined packages (this happens sometimes, due to various reasons), please fill out the registration form here, and bring the check / cash to me (I will text you the address).

Last but not least, a special note for those who participated and purchased the workbooks before the pandemic shutdown. The kids were kindergarteners and 1st graders in Spring 2020, and because we have 2+ years break, the kids are 3rd and 4th graders now. They are welcome to come back for testing for bronze or silver medal level tests, respectively. If there is any question regarding their appropriate test level, or proceed further along in the program, please let us know (again please note the contact info above).

Overview

The kids will practice their workbooks at home. I probably should emphasize that for many kids, especially at the beginning, parents will likely need to get involved, mainly via encouragement, also check the work to make sure the kids did it correctly. The test will be held on (most) every Tuesday morning at about 8:15 to 8:45 am, before school. Once the kid completes the workbook, and passes all the tests in a medal or trophy level, the medal or trophy will be awarded.

The test emphasizes both accuracy and speed on math facts. There are some problem solving (word problem) at the trophy level (platinum, fraction, decimal and percents). For blue ribbon / bronze level there are addition and subtraction, for silver and gold there are multiplication and division. The workbooks for blue ribbon / bronze medal level are the same, ditto for silver / gold medals. The bronze and gold level tests are 2 minutes long, silver is 3 minutes. I think they all have 18 problems. All trophy level tests are 3 minutes. At platinum level there are sometimes two approaches to perform calculation: the traditional method which is more commonly taught and used, and the mental approach which basically we do it in our mind (our heart) without writing out the intermediary results during calculation (sometimes we call it borrowing or lending). Those distinction sometimes caused confusion for the kids, and if parents need some more explanation, please let us know.

The skill levels is explained here. Please note Math Fact Scholars program is owned by Math Fact Scholars, LLC. SSA is just helping run it at Spoede school.

Volunteered needed: this cannot run without volunteers. We need volunteers to run the test: grading, manage the test box, help filing the test papers, to the backend work: processing the order, ordering the workbook and testing copies, reviewing the test papers, and recording them in the google spreadsheet that we publish etc.

PS: obviously math and problem solving are important for kids academic and grownups career / daily lives. I am a strong believer of math, you can see read from my recent post here. At the same time we need to keep in mind math facts and speedy calculation are just a part of the equation (no pun intended). Each kid develops in her / his unique, as parents we should encourage our kids to try harder, at the same time don’t be overly zealous when we saw a friend of our kid got some medal or trophy. At this day of age of Facebook, Instagram, TikTok and so on, I just want to put it there and make sure parents put thing in perspective.

A run group for LMS 7th grader kids (or 6th, 8th grade kids, or kids, siblings in similar age range)

Reading Time: 4 minutes

Any questions please let me know || Mobile: 314 540 2721 || Email: minjie.xu@gmail.com

(Update 11-18-2022) We ended the daylight saving time for the year. The sunset is usually at about 5 pm, thus 4:30 pm starting time will give about 30 minutes time. More importantly, the weather is becoming a bit cold as the winter sets in. I think we will pause the run / walk for now. I will thinking about and we can discuss what’s the best suitable activities in the winter months.

(Update 09-30-2022) Last Friday the shower ruined it. Let’s resume today, it seems the weather will be nice. Of course with #stlwx, weather forecast is really hard, as it could change in 5 minutes 🙂

(Update 09-19-2022) We had 3 kids + myself for second run last Friday 9/16. I ran a bit but the girls mostly walked. I understand this past Friday we have hot balloon race at FP and other activities for some LMS 7th graders. || We plan to run again this Friday 9/23 at 4:30 pm, same location. Looks like we will have two 3rd graders joining us 🙂

(Update 09-12-2022) First run was a success! We have 9 kids: eight 7th graders and one 2nd grader (sibling), and a few parents (grand parent?). The boys are more determined 🙂 || We plan to run again this Friday at 4:30 pm, same location. Looks like we will have two 3rd graders joining us.

(Update 09-08-2022) We plan to run at Malcolm Terrace park (11370 St Paul St, Creve Coeur, MO 63141) on Friday 09/09/2022 at 4:30 pm. Everyone is welcome to join. Bring a water bottle, or a towel for wiping sweat, and note the restroom at the park is open.

(Original) I moved the “running” discussion from the FB Ladue parents community group here. I said 7th grade because my daughter is a 7th grader. The runner2runner program cutoff is 6th grade. At 8th grader I noticed LMS has a program for cross country. Our intention is NOT to compete against other programs.

Note this group is open to everyone in the community in this age range; so please feel free to forward to anyone may be interested too.

Goal – our main goal for our kids is to get some exercise and also have some fun. The main goal is not to prep for a competition or for a race. This is organized by parents and we don’t have formal accompanying materials such as “Girls on the run” etc. If our kids can breeze more fresh air and get close to nature more, that’s a big win for all of us.

Venue – I am thinking Malcolm Terrace park (a trip from the parking lot near the playground then back is about 1 mile, 80% of the trail is not paved); Venable Park (0.5 mile per circle, paved trail). Another park I can think of this the Tilles park trail (paved). Stacy park can be a choice when the renovation is done. I think we (coach Huang and parents) can jointly decide the location. My thinking is we take baby steps to get started. The reason I am thinking parks or tracks is I want to avoid running on the roads with car traffic.

Time – we need to agree on a time slot (or 2 time slots) each week, and hopefully with two time slots it will make it easier to get the busy middle schoolers / parents to participate. I understand pretty much everyone is busy: due to other extra-curricular activities. At this time it seems Friday afternoon is a decent compromise for some kids. As of 1:40 pm 09/06 Tuesday it seems we have at least 5 kids, 3 boys and 2 girls for Friday afternoon run. We will likely have some grownups joining us too.

Items needed – running shoes, if possible (also depends on where we run, trail running shoes, we can talk more later), water bottle, running shirt / shorts / pants suitable for running. Most important of all though, is an open heart and mind to participate.

Coaches
Jiansheng Huang: proud Laude dad. His older daughter (LHWHS alumni) graduated from medical school at Wash U this year and is starting her first year of fellowship. His younger daughter is currently a senior at Ladue High. Coach Huang ran a few Marathons including Go St. Louis, Chicago Marathon, NewYork Marathon, and he qualified for the prestigious Boston Marathon in recent years. Mr. Huang will teach all things around running including prep and cool down, safety etc, and he will likely lead the pack during our run too. Note: coach Huang will show up once we get more serious about running. He probably won’t show up if we just walk.

Minjie Xu: yet another proud Ladue dad (Serenity 7th Spartan, Sophia 3rd at Spoede). Minjie started running (or jogging about 5 years ago, with the main goal to keep weight in control (and be healthy and fit). So far Minjie ran 3 half marathons in St. Louis area (1st run was a week before pandemic shutdown in March 2020). Minjie will likely run and walk at the end of the pack to keep things in check.

It will be great to have mom(s) participating, especially if the most participants we have are girls… 🙂

Thanks and please let me know what you think.

PS: note other kids in age range in the nearby schools in the community, my only ask is whether you can help look for outdoor facilities for the kids to run safely (outdoor track etc). We will likely start on the parks at the beginning though, at least this is my thinking.

Other running groups or resources for the kids

runner2runner: for kids from 1st grade to 6th grade (peachjar flyer here).

GirlsOnTheRun: in addition to run, there are some talks (or accompanying materials) They have two levels: 3rd to 5th, and 6th to 8th.

Let Me Run: boys equivalent of Girls on the Run above.

Middle school after school activities

Reading Time: 4 minutes

A.k.a., the enrichment opportunities, as they usually call it in the elementary schools. For middle school, though, they usually have more choices than elementary school. This is the Ladue Middle School current offerings. Note the Science Olympiad itself has 20+ subjects / events, and it’s mind boggling to say the least. Also note I was taught in the motto of “学会数理化,走遍天下都不怕“ (this is google translate: “Learn mathematics, physics and chemistry, travel the world without fear”, not perfect translation, but I think the readers got an idea 🙂

When I was a middle schooler

The after school activities reminded me something I did and liked when I was in middle school, we call it 兴趣小组。I recall a few groups, such as aerospace, computer (started at grade 7), physics (started at grade 7 as well). In theory we should have math competition too, but our counselor + math teacher is one of a kind, he essentially make the whole class (or most of us) do the math competition, at least at the first round. I had fun doing basic programming using computer similar to Apple II (we had one Apple II, then other similar computers). I also had great fun in my physics club field trip at then 宁波高专 or 宁波师范, note my teacher 姚仁汉 is one of a kind, and he passed away in recent year. I did okay in Math. At high school I continued the math competition, because my math teacher at my 1st year of high school really liked me, and encouraged me to do more. It got extended to the 2nd year, and I even did some math competition training in the summer between the 1st and 2nd year (I think it was again due to my then math teacher liked me and he made the recommendation, I vaguely recall his name is Chen Bing 陈斌 and here is one of his article), offered by another good math teacher. But I kinda wondered off after that, because I did not like the style of the math teacher for my 2nd and 3rd year. I think similar can be said for physics, the only difference I do have a lot respect for my physics teacher.

Today’s challenges

Back Serenity’s after school activities, she did a few easy ones (lower frequency for meet, or extra time to work on projects) last year, as this was her first year at middle school, we thought take the pace. Now this year we hope she can do more. I don’t necessarily want her to compete in the math competition, or for that matter, in the Science Olympiad. But I do hope she can get some of the exposure I can when I was in middle school: it really can be anything, and I do understand she does a lot music related activities (choir and percussion) outside of the school. I am trying to get her some STEM exposure.

One thing I noticed is because we are at a very good school in the state, with good reputation in the STEM area, that also raised the bar. In other words, she may not get opportunity to represent the school because the competition could be tense. I am not overly concerned on that. I think in this generation, the me generation or the iPhone generation, some of they probably don’t care much about competition anyway. And also, ultimately we are only compete against ourselves. Be the better of ourselves. Resist the temptation of binge watching Netflix, or doom scrolling TikTok, YouTube, twitter, facebook (put in your favorite social media stream there). As long as the kids are productive, and learn something everyday, as parents I feel good about. I don’t this is the time to be their lives’ highlights yet. They have long road ahead of them, life is a marathon, not a sprint, as the old saying goes.

On the flip side of all this technology advancement, I also saw a lot more opportunities that kids can learn. The Youtube video and google search are two very popular choices. And some curated content sites such as thekidshouldseethis, and Khan Academy are excellent choices too.

Signs your kids (or you) may have too many extra-curriculum activities

I recall years ago, when Serenity was still a toddler, or a preschooler. One Saturday morning, when we were at Thies farm Pumpkin Land at Maryland Heights, I got a call from my eye doctor office. It was about my wife’s and my annual eye exam. We totally forgot about it. Two things came out of it. One is I realized that we were probably overwhelmed by child raising and work. Although looking back at the time we only had one kid, and maybe work is taking too much effort and attention. Another thing is I realized that I need to put everything on google calendar with reminder. I think I was using Yahoo calendar then and I was not sure I put the eye doctor appt on electronic calendar (not to mention reminder).

Years later, over the summer, I heard a story from a mom that she gave a music director last minute notice about a schedule conflict for her kid, and the director was not happy. This made me thinking how much activates that I want Serenity / Sophia to have. Ideally no such conflict, or very few / rare 🙂

PS:

I realized over the years, I was probably over-zealous on Serenity and Sophia’s extra curriculum activities: this includes sports and things like math (extra math). Math is a very common headache, bottle neck for many kids and families here. I will need to set the right expectations, set priorities, regroup and so on. Serenity is actually doing fairly well on a few things she likes: choir, percussion, just to list a few. I don’t necessarily need to see her winning a chess championship, play the guard for the school basketball, or soccer team, or winning medals at the Science Olympiads to be even prouder dad (I am being sarcastic, self deprecating to myself). For that matter, I did not necessarily achieve all the above I just mentioned, when I was in middle school. Also I also recall one of my bosses once said, don’t try to be someone else, just be yourself (I have quite a few disagreements with him when I was working here, but this one stuck 🙂

On the other side of spectrum, my wife probably get ahead of herself on Serenity’s math. I think she wanted her do one of two things, both are hard. 1) Math acceleration, basically jump grade (跳级) on math; 2) Participate in math competition. I also speculate her emphasis on math and to some extent on science was probably due to her own lack of confidence on the two subjects. She chose 文科 (liberal arts) in high school, basically did simpler math, and did not do science (physics, chemistry and biology). Now she wanted her daughter to do the opposite. Sounds familiar? Yes, last I recall there are lots of Chinese American parents who did not go to ivory league colleges, wanted their kids to go when they grow up 🙂
