These are two different sets of 30 cards for the classroom game "I Have, Who Has?"
Set 1: 30 cards Adding double digit number with a multiple of ten
Set 2: 30 cards Adding double digit with a single digit
I copy these on different colored card stock and laminate.
My class keeps track of how long it takes them to get through the set and we keep a running time on our whiteboard.
Great for 2-4 grade.
