#### Objectives

After successfully completing this activity:

• Given a two dimensional view of a building, the student will select the corresponding 3-dimensional image (how the building looks if it is viewed from the ground).
• Given a variety of 2 dimensional shapes within a map, the student will demonstrate knowledge of the definition of a polygon by correctly identifying the shapes that are polygons.
• Given an overhead view map, the student will correctly identify the number of sides of a given polygon and its corresponding name based on the number of sides.

#### List of Materials for Group Activity

• Large sheets of paper
• Colored pencils or other drawing tools
• Optional: stencils of various shapes for drawing landmarks, building features, etc.

#### Generating Problems for Additional Practice

• Take a walk around the school's playground or neighborhood. Ask students to discuss and reach a consensus about what various items would look like from the air (buildings, trees, mailboxes, etc.). Keep track of how many of these objects are not polygons, and how many represent each type of polygon (triangle, quadrilateral, pentagon, etc.).
• Using a Web search engine (Yahoo, WebCrawler, etc.), do a search on the words "aerial" and "view." Using these images, try to find and identify as many polygons as possible.
