Today we were working on adding numbers to 100 with regrouping. We were practicing by using base ten blocks, first as a class on the SmartBoard, and then in groups as we played a game. Here is the link to practice adding with base 10 blocks.

Change the number of columns to 2 to only have 10s and 1s. Have fun regrouping!
