Display a completed Flatopia Polygon Zoo. Display one of the shapes from the quadrilateral Shape Sort Cards from Lesson 5.
- Where does this shape belong in the zoo?
- How did you decide?
- Does everyone agree?
- Can this shape belong to another category?
- Can this shape be described as a [trapezoid]?
Propose that students are going to add some shapes to the zoo.
- Where would a 10-sided shape (decagon) go? Explain your reasoning. (In a new section near the hexagons and pentagons because a decagon is a 10-sided polygon like a hexagon is a 6-sided polygon.)
- Where would a cylinder go? (Not in the zoo, it is not a polygon.)
- Where would a cube go? (Not in the zoo, it is not a polygon.)
- Where would a circle go? (Not in the zoo, it is not a polygon.)
