Plus 1 / Minus 1 Bingo

Math on Friday was a fun Bingo game!  Students worked in pairs to get a "bingo" on their boards by covering various numbers. But it wasn't just the number on the card that they flipped over!  They had to first add one on to that number, and then subtract one from it, and  only then they could could cover one of those new numbers!  A lot of steps and keeping track of their work!  As well as team work and checking up on each other!
