Yes. What we learned from analysis of Singapore math, it’s a system and each element - curriculum, pedagogy, assessment and professional support - must be strong and aligned. Merely changing courses won’t move the needle and my preference is to start with support and pedagogy.

So much to unpack here, none of which fits a tweet, but in a nutshell, let’s give 6-8 three full years with the wise allocation of sensible algebra per the CCSSM and then combine Algebra 2 and Pre-calculus for any 11th grader who wants to do Calculus as a senior. Just sayin’.

Exactly! Which means, using a little common sense, a lot more data, statistics, modeling and technology, and a lot less of what continues to pass and poison as Algebra 2.

Join me and watch the facial expressions and body language of kids in any classroom doing Mad Minute timed drills that send an offensive message that speed and accuracy are all that matter.

Thanks Todd! Fun to reread 30 years later. Looking for why math is still a mess, try lasting truth of: “Nor is this about abandoning computation, which remains an indispensable part of the mathematics program, so long as it is done mentally, with a calculator, or via estimates.

Yup. Thanks @ToddTruitt76508
Definitely worth a listen even if I say so myself.

@steve_leinwand Words to live by as a math educator #mathchat
I committed a severe act of self indulgence, reflecting on 'Necessary Conditions', which came out 5 years ago. emergentmath.com/2023/09/01/nec…
You think this dude is a tad agitated? Duh.
Let's talk about AP PreCalc! With @steve_leinwand and more! NEW EPISODE this Thursday #DebatemathPod
The reverse is fun too when the 8th gr comes in and sees 5th gr work. “Oh I wish we were still doing that! It was so easy.” I’m like ya, but remember when you thought that was hard? Samesies… you’ll look back at this stuff the same way soon!!
Personal choice PD heading into February. Looking forward to being challenged by @steve_leinwand and @drMi #InvigoratingMath
My father and his expression cannot be missed in this photo. He took us all to Mexico for the 4th and last time. He wanted to do one more family trip. He’s in good health. Just too old to travel. Cannot think of a better last memory vacation photo with his whole family❤️
@AllLearnersMath @moymathvt @MathWithDignity Omg, SO many people! @BBlankePhD @HiMsKelly @MandyMathEd @steve_leinwand @AnnEliseRecord @drnickimath @Mathbitious @mburnsmath @cmadancy @ahosmath9 @MissRashbaMath @Zakchamp @joboaler @Indispeaknteach just to name a few!
@mathillustrated @steve_leinwand If they took their own APStats class (a choice in line with many students' aspirations) they'd be clearer about the difference between correlation and causation.
@gregbudzban Too much content to address. Got to make choices. Easy: show the graph of sine, look at AROC, create graph dynamically. Lots of meaning. I leave sine proof for individual investigation.

Need another reason to dismiss some of what is labeled “cognitive science”?
“We don’t learn by doing. We learn by thinking.” One of the best presentations on cognitive science I have seen. Thank you @hruizmartin
Ready for a parent coffee talk about building understanding in math with @HKIS How has math changed? What changed? What is fluency? #iteachmath #numnersense @fayleong
@Mathowitz @steve_leinwand CB responds when colleges say "this curriculum doesn't align with our courses and thus we will not accept credit." Honestly, we all know college acceptance is a game. And it's a game designed by colleges. That's where I would ask for the reflection.
@brightmorningtm @BBlankePhD @frantoon57 @Dr_John_4_Math @mburnsmath @SueOConnellMath @steve_leinwand Thank you all! Appreciate you all so much.
Hey #CMCMath! Looking for a 3:30 Friday session that will stimulate your mind and change how you think about PD? I’d love to see you in Renaissance Ventura. Let’s talk about how teachers are the solution to our broken system of PD. Leaders and teachers are welcomed. #iteachmath
@steve_leinwand Good call! This letter contains exactly my sentiments about math education in America. We have to help people understand what are strong mathematical skills. It is not a list of math topics. It is a list of learners characteristics & adaptability to problem solve.
@steve_leinwand appreciate you continuing to be a voice of the people, Steve...couldn't agree more on this being a money grab.
We expect more from the College Board. The proposed AP Precalculus is a misguided money grab with harmful impact on school mathematics. See our case in this open letter and, if so inclined, retweet and/or add your name as a math teacher for change: drive.google.com/file/d/1wAbdZp…
