Target had these bingo boards on sale earlier this week so I bought a bunch.

I had this idea a while ago for a review activity built around bingo. I generated a bunch of bingo cards with the numbers -11 through 12 (plus a free space) that would fit into these bingo frames. I printed them double sided, and laminated them before creating a ppt file with some quadratic equations on it.
Kids solve the quadratic equation on a whiteboard, and mark down their answers by closing the little windows on the bingo boards. (If they get +8 and-5 as solutions, they would close those frames on the bingo board.) It works well with quadratic equations, because each problem they solve, they are rewarded with two frames, and solving FAST is not nearly as valuable as accuracy and choosing a lucky board. I think it will work well with traditional linear equations too, but that’s an application that I will try next year! Slides and bingo boards are below!
