Two Pizzas and Five People

I’m thinking a lot about how my 6th graders responded to a pre-lesson task in “Interpreting Multiplication and Division” — a lesson from Mathematics Assessment Project (MAP) . MAP lessons begin with a set structure: Before the lesson, students work individually on a task designed to reveal their current levels of understanding. You review their scripts and […]

If you teach 6th […]

First Day Lessons

I have been doing the same first-day math activities for a few years now. There hasn’t been anything on my radar to cause me to change them, but I’m always looking. However, I’m 100% sure I will NOT be going over classroom rules and procedures. Math 6: Skittles Here’s the Skittles_Lab handout. I have to tweak this activity to incorporate TinkerPlots — […]
