Last week, the Bibliophile found a Math Bingo game I had hidden in a box of "for later" materials, but he was adament that he wanted to play it. It contains multiplication and division in addition to addition and subtraction, so I didn't want to open it yet. Luckily, he's easily pacified; I offered to play our own Math Bingo with him on his doodle pad instead. He was all for it. I wrote up a very quick chart and kept it simple. The only addition and subtraction involved + and - the numbers 1 and 0. We just asked Daddy to randomly call out numbers 1-9, and put quarters on the squares as he figured out where they went (sometimes with a little help).
Feel free to use this printable (slightly different than our prototype, but same idea), if you think you'll kids will enjoy it. I still don't understand why Scribd seems to lose the grid lines when I upload pdf's, but you could write them in I guess (or maybe it prints fine? I need to test it).
I am linking this post up with Math Monday.
Comment: Have you done any fun math related activities with your kids this week?
