This game is to help with subtracting from 20. The file has 32 pages with 6 boxes on each page. Each box is dedicated to a subtraction problem under 20. Simply cut out the boxes and place the 6 pages you'd like to work on in a large cloth cube. Have the students roll the cube and tell you what the numbers subtract to. To reinforce the subtraction statements, you could even have the students write the subtraction sentences with the answer.
