I have posted a video of how to proof draw a subtraction problem, with regrouping. I have given the students a “Bonus Homework” sheet to do at home tonight. They need to show you how to complete it, using proof drawings! Below is a demonstration of what this means. This is a fun, visual way to demonstrate subtraction with regrouping, enjoy!
