This robs students of everything mathematics should be… The “real world” connection The step-by-step procedure Circle the numbers you need to solve the problem The pseudo-context word problem. Lesson 19.2 infers that this unit is front-end load with...

I’ve recently spent a lot of time visiting 3rd grade classrooms as they begin to dive into division. Here’s what I encountered on one of my first visits which was a crippler for everyone involved. Saw this today & was crushed. For the record…this...
Cheese Mover, Math Tools, SMPs, Technology, Who Knows?
I’m continuously reminding myself that I need to be a “wise consumer” of math resources. Whenever I’m asked to review a resource, I reach for the Standards of Mathematical Practices. The SMPs are like Kryptonite and will break down even the...
