This download contains a direction sheet and 24 playing cards for subtraction concentration. The facts included in the game are all problems that ask students to subtract two-digit from two-digit numbers in situations where they must regroup/borrow in order to find the solution.
How to Play:
1. Cut out playing cards.
2. Lay out cards face down in two separate groups – one for subtraction problem cards and one for answer cards.
3. Flip over two cards – one subtraction problem card and one answer card. Solve the subtraction problem and see if the difference matches the number on the answer card.
4. If the cards are a match, set them aside. If they are not a match, flip them back over.
5. Play until all of the problems are matched up with their answers.
