Here’s a super easy and fun way to reinforce attributes of polygons. Using a rubber band that is not too small or thick, students create shapes using their fingers. It’s a great multi-sensory activity.

Ideas:
-show me a triangle
-show me a triangle with one obtuse angle
-show me an iscoceles triangle
-show me a quadrilateral
-show me a trapezoid
-etc.

Shapes larger than a quadrilateral (4 sides) are more difficult to make. Students can partner up to make pentagons and possibly hexagons.
