A drawing showing one hundreds block, two tens rods, and three ones units.

Explain how the base-ten blocks you drew in question 1 relate to the expanded form you wrote in question 2.

The hundreds block represents 100, the tens rods represent 20 (two tens), and the ones units represent 3. These correspond to the values in the expanded form.
