How can we classify polygons?

• What are the names of these polygons?

• If the class is struggling with the third shape, ask the class to count how many sides the polygon has.

• What other 6-sided shape have you seen before?

• One of these hexagons is familiar to you. The other is not as familiar, but it still has 6 sides.

• The word hexagon actually means “6 sides” – hexa means “6” and gon means “sides.” Since both figures have 6 sides they are both hexagons.

• Can someone show us another hexagon?

Hexagon

Names for Polygons • Polygons are named by how many sides they have. Poly and gon are from the Greek Language meaning “meaning” and “sides.”

• What other words do you know with these prefixes?

Making and Naming Polygons • Today you will create new polygons with different numbers of sides.

• Let’s look at these two polygons…

• How can you arrange these two polygons so the outline of the final shape they make is a polygon?

• Examples:

•What are the names of these new polygons?

Triangle Quadrilateral Hexagon

Making and Naming Polygons • Is it possible to make a new polygon with these two shapes without having sides from each of the original polygons lined up exactly?

• Example:

•What is the name of this new polygon?

•Is this shape a polygon?

•This is not a polygon because the shape is still two distinct polygons, each with its own set of sides and vertices.

Making Polygons Combine two or more polygons to make up other polygons, based on the instructions below. Once you have created your polygon, trace the shape and name the shape. Use dotted lines to show the polygons you used the create your new polygon.
