Practice decomposing numbers with this activity that has students splitting numbers into parts.

## Decomposing Numbers Hands-On Math Activity

This activity is designed to help students consolidate their understanding of decomposing numbers. Students randomly choose a number between one and twenty and then create it using colored blocks on ten frames. They use two different colors to represent the whole number. Then, create a number sentence demonstrating the part, part, whole they have created in the ten frames.

Through this activity, students will show their understanding of how to break apart a whole number into two different parts.

## Tips for Differentiation + Scaffolding

A team of dedicated, experienced educators created this resource to support your math lessons.

If you have a mixture of above and below-level learners, check out these suggestions for keeping students on track with the concepts:

### 🆘 Support Struggling Students

Give students physical counting blocks and begin with a part rather than the whole.

### ➕ Challenge Fast Finishers

Have students who need an extra challenge create as many different combinations of parts as they can. Ask them to record each equivalent number sentence.
