I just played this with my resource students this week to review rounding to the nearest ten, hundred, thousand, ten thousand, and hundred thousand and they LOVED it!
The caller reads the problem. The players round the number and find the answer on their BINGO board.
This 10 page file contains 10 BINGO cards, calling cards, and an answer sheet.
I printed the cards on a color printer on card stock. I laminated and then, cut out.
Hope your students have as much fun as mine did!
