Want a new way to practice math that is engaging for students? "This or That" is an interactive assessment! Through this game students can show you what they know about units of measurement by holding up their auction style paddle showing the unit they would use to measure a given object. My students LOVE this game! This edition includes the materials needed to practice kilograms/grams and pounds/ounces. I have included both color and partial color copies.Your students will love this new form of review!
