This is a geometry activity that has students explore the properties of two-dimensional shapes. This activity can be done individually, with a partner, or in a small group. Students can be directly taught the properties of two-dimensional shapes first, or this can be used as an exploratory activity. Students' thinking about shapes is challenged in this activity, as the opportunity to consider more than one name for a shape is presented. (example: a square can also be called a rectangle and parallelogram, but why?). As always, I try to keep my resources clear and to the point.
