What Is an Addition Fact?

The definition of an addition fact is the "sum of two specific addends that will always equal the same result." For example, 3 + 4 will always equal 7, and 2 + 3 will always equal 5.

Addition Facts to 20

It's common to start by teaching students the addition facts to 20 which is another way of describing the sums from 0+0 up to 10+10. This is a good starting point for first graders.

Why Are Addition Facts Important?

When students memorize the basic addition facts, they store those details away to use as they advance to more complicated math tasks. They can then recall these addition facts when necessary while their brain can focus on more advanced math processes.
