Number rainbow and fact families with 14

This video helps students practice subtraction facts where you subtract from 14, such as 14 − 6 and 14 − 9. For that, we use both fact families with 14, and a NUMBER RAINBOW.

In the number rainbow, we connect two numbers with an arc if their sum is 14. This visual tool clearly shows students how the numbers are paired to make 14.

We also briefly go through all the fact families with single-digit numbers where the sum is 14 (one with 10 + 4, another with 9 + 5, then one with 8 + 6, and one more with 7 + 7).

Lastly I drill the viewers with the subtraction facts — Mathy joins in that also! I pause for a little while to let children answer the facts — thus this video can take the place of drilling by a teacher.
