Description: Help students in middle school match equivalent models and representations. These cards require kids to match cards with formulas and expressions for area or circumference as indicated by A or C and shading or outlines. Use after introducing the formulas. The cards show models, expressions, and simplified expressions (or values). Students get LOTS of practice as they select two of six cards that represent the same value. Among the six cards shown, there could be a model matching an expression, a model matching the final value (which encourages mental math), or an expression matching a simplified expression. This effective research-based activity is fun for class discussion, or for individuals, partners, or a student working with an aide or tutor.
