About this worksheet

What students practice

  • Students use equivalent ratios to convert length, mass, volume, and time measurements.
  • Students change measurement units when multiplying or dividing quantities.
  • Students explain why measurements need compatible units before calculating area.

How to use

Use after introducing equivalent ratios. Keep the conversion reference visible, and ask students to show unit conversions beside their calculations.

Curriculum

Common Core standard covered

6.RP.A.3.d

Use ratio reasoning to convert measurement units and to change units when multiplying or dividing quantities.
