How Number Bonds and Missing Addends Help

Why teach number bonds?

Number bonds are an effective way to help children master basic facts. The largest number in a number bond is the whole. Each of the smaller numbers in a number bond is a part. Students learn that two parts equals the whole. The whole minus one part equals the other part. Number bonds lay the foundation for mental math and problem solving.
