How to Make a Math Game?

I used to play a really fun game in school called ‘math bingo’. We used construction paper and markers to make regular old bingo cards with numbers in each square. Anything can be used as bingo chips. The teacher would then write or call out math problems, but not the answers! We had to answer the problem in our head or on paper, and see if we had the answer on our card! So if I were to say ‘5+5′ and you had a 10 on your card, you would mark that one off. Have fun!
