Allot of students have a hard time learning the metric system, because they forget very easily the factor number, prefix, symbol, and base unit of the metric system. To help students with recall of this information, this document is design to helps students identify the prefix, symbol, and base unit of the metric system. As the teacher, you can design a game in multiple levels ether as flash cards, the game memory or any thing else. It really depends on how you create your cards. In my class of 7th graders, I made a set of twenty metric system memory cards by gluing each card to a black construction paper boxes and lamented it (for future use). I had students lay their cards out, so only the black was showing and they had to find the question and answer question. It’s a fun was to start a concept after an introduction lesson. After I realized they had a basic understand I had them apply concept by doing a lab.
