Counting On and Counting Back

Counting on helps you add by starting from a number and counting forward. Counting back helps you subtract by starting from a number and counting backward. These tricks make math faster and easier!

Examples

  • Start at 6 and count on 3 more fingers to reach 9 for 6 + 3.

  • Start at 8 and count back 2 to find 8 - 2 = 6.
