# Decomposing Numbers

### Teachable Moments: Shake Rattle Drop and Friends of Ten

Teaching combinations of 10 - a fun way to teach kids about all the different addition combinations that equal 10. This activity also provides a great introduction to the commutative property of addition, which says that when two numbers are added, the sum is the same regardless of the order of the addends. #handsonmath || Gift of Curiosity
