Jump Strategy, we can also count by 2s or 10s, or make any “jumps” we want to help us solve a calculation.  Using a Number Line or Number Chart. This is a very popular and visual way to help students work out subtraction problems. enVision STEM Project: Material Math Find Out Collect different types of paper. Talk about the uses of paper.
