Number bonds

Last week we began working with number bonds. Number bonds are a way to think about numbers as parts and wholes, and will provide a strong foundation to build on when we begin addition and subtraction.

This week the students began by working with snap cubes and breaking them into different parts to find different ways to build 9. Look at all the ways we discovered together:

Next week we will also use a math balance to find parts and wholes to make more number bonds. It's week the students just explored this tool so they will be familiar with it. 

Ask your student to tell you more about number bonds, and explain their understanding.
