Subjects: math

Grades: 4,5

Description: This is a good way to reinforce the properties of 2D shapes. Using Which One Doesn't Belong? students will read the 4 possibilities featured in the first 10 cards and then eliminate the wrong answer. The second set of cards is a visual of 2D shapes using both regular and irregular polygons. Students will determine which one doesn't belong based on the property featured. Terms such as vertices, sides, angles, regular and irregular polygons are used. A great way to end a unit on 2D geometry.
