This FREE set of cards will help students compare rectangles with the same area but different perimeters, important for CCSS 3.MD.8. The dimensions of the rectangles have been carefully selected to encourage students to see relationships and make generalizations.
These cards are aligned to Common Core standards. Descriptions of related Grade 3 resources are included in the file. This card set is also part of a Grade 3 bundle and the Games Galore bundle. Thanks for looking!
