This is a two page reference guide that provides visual representations using bar models of the units to show relationship comparisons between units. Each page also provides a quick summary of the conversion steps for both customary and metric units. The simple process of multiplying when you move from large to small units and dividing when you move from small to large is presented along with the familiar mnemonics device; King Henry Died Unexpectedly Drinking Chocolate Milk. The visual elements helps students who are still transitioning from concrete to abstract understanding of measurement units and relationships and the top margin makes for easy hole-punching to use in notebooks. Copying two sided and laminating the product would allow students to use dry-erase markers to mark off units and identify equivalencies so it could serve as an ideal tool for small group math intervention as well!
