This is a hands on activity for students to practice adding or subtracting WITH regrouping. This activity can be used as a math game or center. I used it as a closing activity with my guided math groups. I watched students and used it as a formative assessment to see if they could correctly add or subtract using multiple strategies.
This 12 page packet includes
-16 addition and subtraction cards with answers on the back
-blank cards for teacher to create own problems
