Students work with congruent, similar, and not similar pairs of shapes. Students cut out pairs of shapes and sort them into groups-- congruent, similar, or not similar. This is a fun way for students to practice comparing shapes.
There are also a few not similar shapes that at first might appear similar. However, the angles of these shapes are not the same, in kid terms one might say one shape is "skinny" and one is "fat." These shapes can lead to a rich discussion of exactly what similar means.
