Here’s a great activity to help your students really learn about Metric Units & Metric Prefixes, by simply asking them to spend some time coloring images that represent each of the basic units and prefixes used in this system. By having your students spend time thinking about what each image represents, they will develop a more meaningful understanding of this global measuring system.
This activity will make it much easier to memorize the units and symbols used and retain that knowledge for a much longer period of time. Ask your students to discuss what each image represents and see if they can create ways to personalize them. Emphasize to your students that spending time to truly understand something, is actually a lot easier than memorizing and forgetting year after year.
