Han and Jada represented 700 using different base-ten blocks. Then they each started a base-ten diagram to show their work.

Jada

Han

Jada only used hundreds.

Han only used tens.

1. Use base-ten blocks to show how Jada and Han each represented 700 with their blocks.

   

2. Explain how you know both ways of using base-ten blocks show 700.
3. Complete Jada’s base-ten diagram.
4. Why do you think Han’s diagram would take longer to finish than Jada’s?
