### Subtract Numbers within 10 Vocabulary

Directions:
Name the parts and the whole for the group. Then complete the number bond.

Explanation:
Number bond:
A number bond is a simple addition of two numbers that add up to give the sum. Using number bonds, one can instantly tell the answer without the need for the actual calculation.
Whole: Here we know that 5 is a whole number. The number 3 combines with other number 2 gives the result 5.
Parts: A number can be thought of as a whole made up of different pairs, or parts, added together.
