This is a division bingo game with 50 problems for each number (1-50). The problems have 3-4 digit dividends and 2 digit divisors. There are 30 unique cards included that can be printed and laminated or put into plastic covers. When playing with my class, I usually write one problem at a time on a piece of paper under the document camera and give them about one minute to solve. If this is a new concept, I would model how to solve some of the more challenging problems. I usually will write the next problem underneath the previous one and have 3-5 problems displayed at one time for slower students.
