35 Bingo Cards included! Project the slide and your students will add or subtract 10 or 100 from 2 and 3 digit numbers. Included are a completed 100's chart as well as a fill-in-the-blank 100's chart. Use for students that need the visual representation. Game is included as a PDF and as a ppt. in case you would like to put slides on a timer!! My students beg to play this game, and while playing they'll do more math operations in this simple game than they would on any worksheet. Instructions for Bingo included. After playing Bingo once a few days later we reviewed again by racing to find answers. Both ways are a great review of adding and subtracting 10 and 100!
