I have 3 shapes in my bag. Together they have a total of 16 sides. What shapes could be in my bag?

Display Polygon Names poster for students and discuss the names and shapes they are already familiar with. Show pictures for those they may not have seen. Cards are included for the discussion.

Students determine combinations of shapes that meet the given criteria. Have students explain their answer by stating the names of the shapes, number of sides, and an equation.
