Backwards Bingo is just as fun as regular bingo, but your students will be even more engaged! The students work out the problems individually and cross off squares on their bingo cards. When a student gets a bingo, they raise their hand and call out "Bingo!".
This bingo challenges and reinforces estimating 2x2. The students must round each number and then multiply the two numbers to find the estimate. Let the fun begin!
