This is a Decimal Bingo game in a Powerpoint presentation. There are 6 slides and 50 problems for numbers 0.01-0.50. I have students make their own bingo cards on pieces of graph paper. The first slide gives students directions on what numbers can be in each column. I think having them make their own helps their number sense (and makes less work for you). This is animated so that one problem appears at a time (with each click) and 10 problems are visible on each slide (for slower workers).
This includes mostly adding and subtracting of decimals, with some multiplication and division.
