Addition Fact Patterns
Key Concepts
- Addends and sums.
- Use the addition fact patterns to find the sum.
Introduction
Addends
Addends are any of the numbers that are added together. For example: In the addition equation 8 + 3 = 11, the 8 and the 3 are addends.
Addition:
Example 1:
Find the addends and sum for the equation given below.
3 + 4 = 7
Solution:
3 and 4 are addends.
7 is the sum.
Example 2:
Find the addends and sum for the equation given below.
9 + 5 = 14
Solution:
9 and 5 are addends.
14 is the sum.
Use the addition fact patterns to find the sum
Example 3:
Find all the ways to make a sum of 5. Identify the pattern it makes.
Example 4:
Find all the ways to make a sum of 9. Identify the pattern it makes.

Use fact patterns and complete the equation.
10 + ____ = 16
9 + 7 = ____
____ + 8 = 16
7 + ____ = 16
6 + ____ = 16
