Adding three addends involves combining three numbers to find their sum. This can be done by adding the numbers in any order, and the result will be the same regardless of the order of addition.

Strategies for Adding Three Addends:

- The way in which numbers are grouped in an addition problem does not affect the sum. The students can then regroup the numbers in any order they find convenient.
- The order of the numbers being added does not change the sum. The students can then reorder the numbers in any order they find convenient.

Example:

3 + 11 + 7

= 3 + 7 + 11

= 10 + 11

= 21

Encourage students to practice adding three addends with different sets of numbers to build fluency and confidence in this skill. Emphasize that the order in which the numbers are added does not change the final sum.
