This is a great way to get students involved with decimal operation practice. The game boards can be printed on legal sized paper and the students get to create their own unique boards. The Answer Key has the problems and answers that I would pull out and read. I would also write the problems on the board to that students who are little slower with their calculations could still catch up. It also includes a few problems where students need to turn fractions into decimals.
Bingo is always a hit!
