Use this worksheet with students to work on learning the metric system! Included is a phrase I use to help my students remember as well as a blank space for them to write their own. After this, I take students outside to find something that is as long as each of the units on the sheet. I ask for 2, though time restraints usually mean we get one. For students who are familiar, they have the bonus of measuring me. Note: before going outside we talk about how the metric system is similar to our base ten system. I usually write the names of each with each other to show the relationship.
