Polygon Land Now, lets have some fun at polygon Land. You'll find hundreds of polygons to drag anywhere you want. Be a creative designer at polygon Land. These are examples of what you can do there. Be sure to read the instructions before you play. Ready? Click here.

41
Find more about 3-D shapes with your partner. Click on the shapes below and print them then follow the instructions on the sheet. Class Activity

42
With a partner, make a chart like the one below and use it to find 3-D shapes around the classroom. Answer each question about the properties of the object and then see if you can correctly identify and name the object.

43
Homework Choose a 3D shape and design a promotion poster for it. What makes this shape special? What are its properties? What is it used for/where is it seen (for example, packaging, buildings) and what makes it a good shape for this use?

44
You made it. Hip, Hip, Hooray!
