Using Triangles to Teach Math Facts – Addition and Subtraction

Here is an illustration of how to use triangles to teach addition and subtraction math facts. See also that the commutative property of addition is embedded in the triangle. Also, notice that the significant number is at the top of the triangle. That is a visual reminder to students that subtraction is anticommutative, rather than commutative.

Thank you Andrew for introducing me to this idea! Next, adaptation for the kinesthetic learners!
