Maths teachers have introduced negative numbers for centuries, to millions of children, with a mountain of cognitive science to hand — and still can't agree how to do it. Debt, a thermometer, a number line you walk along. The arguments are detailed, sincere, and unresolved.
Can't calculate change from a dollar? #iTeachMath
Of course, calculators are to blame!
Or perhaps it's progressive education, famously and mythically rampant in schools across the entire 20th century.
News from 1978:
A nation that has split the atom and sent spacecraft to Jupiter has not yet figured out how to teach all of its adults to fill out a job application or calculate change at a checkout counter.

🏀Texas teacher @math22_miss has a hoop-tastic math activity for your learners at school or at home.
It’s nothing but net! ⛹️♂️

ALT This image features an educational activity titled "Trashketball" for practicing decimals. It involves dividing students into three teams, solving five math problems, and earning shots based on speed. The first team receives three shots, the second two, and the last one. The process repeats for another round. A photo shows students working on math problems at a table. The image includes a thank you message to @MATH22_MISS.
Eureka!
Pundits, do catch up with teachers, and forward your “testing insights on to all the people who think we can fix the "learning recession" by leaning harder into test and punish policies of the past.”

Well, we could stop Jo Boaler style “let them discover math on their own” math curriculums & instruction. That’s great if you love math, but it’s horrible for the students who struggle.
Have you heard of covariation?
I'm loving reading this research. These researchers are putting words to things I've been trying to convey in my PL. Fascinating!

Gene Klotz will be greatly missed by the NCTM and mathematics education communities, his colleagues, students, and friends. #iTeachMathnctm.org/News-and-Calendar/N…
ALT Graphic thanking partner organizations for a nonprofit, talkSTEM, encouraging kids to recognize and appreciate STEM in everyday life. The nonprofit has hundreds of free, virtual stem and math resources on their website and youtube channel. Partners include the national science foundation, southern methodist university, the dallas zoo, the dallas arboretum, twelve hills nature center, the dallas museum of art, the girl scouts of northeast texas, GEMS camp, frontiers of flight museum, st. philips school and community center, and voice of hope. The video accompanying it outlines the importance of curiosity.
Reaching Consensus on curricular and pedagogical matters can improve the effectiveness of a math department and improve student learning. I suggest a pathway in this post.
