One interpretation of Cognitive Load Theory that can go wrong, especially in mathematics teaching. Can you imagine what can go wrong if people who do not math, "simplify" math-ing into the small steps they think are important? #MathIsFigureOutAble #MTBoS #ITeachMath #MathEd

What’s the sum of the products in the 1-9 multiplication table? What’s the sum of the first 9 cube numbers? How many cubes fit in a 9x9x9 cube? Answers might just kick off 2025 in style. #polypad #iteachmath #MTBoS #NewYearMath https://t.co/hOHc1Pj2wT
