This is both a set of 78 different task cards as well as a strategy game: students work in pairs selecting a mental math problem to solve making change, and then use that solution to cover up a square on the game board. They can play on one board and compete to get 3, 4 or 5 in a row, or play on separate boards for "bingo" 5 in a row play.
The cards come in black/white and color; each challenges students to make change using mental math. The goal is to develop a variety of mental math strategies (counting up, counting down, compensating by moving minuend and subtrahend) to calculate various change situations, including the difference between two "tens" (90 cents and 30 cents), tens from other amounts (90 cents and 15 cents) and no tens (72 cents and 58 cents.)
Great for developing mental math strategies. Comes with an answer sheet where students can record solutions for up to 24 cards, as well as "DIY" cards so they can make up their own challenges.
