This number line can be used to count in various ways. Second graders used this number line with their math offices during math rotations. Simply print, laminate, and place in a math toolbox or on a file folder (aka: math office). You could even tape onto a white board. The colors and smiley faces make it easy to count by 5's and 10's. Use a counter to count forward and back. It can also be used for skip counting when learning multiplication.
