There are 64 math task cards (a simple number sentence for multiplication, division, addition, and subtraction).
I use these in two ways. I print them out and put the answers on the back (I also had a team member put a number on the back and provided an answer sheet). I place them in the center of my students groups and if they finish a problem early they always have another problem waiting. I have also used this as a center with the Rally Coach structure. Students work in pairs with one whiteboard (or paper/pencil) and one marker. One student draws a card and the other solves the problem explaining the steps to their partner. The partner listens and praises. Then the students switch roles and continue.
