Texas Gateway: Determining the Perimeter of a Polygon (Series and Activity 1)
This activity provides an opportunity for students to investigate the perimeter of polygons.
Texas Instruments
Texas Instruments: Area and Perimeter of Regular Polygons
Students determine the area and perimeter of regular polygons and use that information to conduct a beginning investigation of limits.
Texas Instruments
Texas Instruments: Finding the Area of Regular Polygons
Students discover a very intuitive method for determining the area of a regular polygon. They use that information to develop the standard area formula.
E-learning for Kids
E Learning for Kids: Math: Dojo: Polygons and Time Zones
Students will play several learning games to explore polygons such as triangles, and how to determine the area of triangles and the different types of triangles. They will also explore time zones.

TOPS Learning Systems
Top Science: Go Figure! [Pdf]
This is a classic area puzzle where polygon shapes are rearranged, giving what seems to be a different total area. Students must try to determine why there is a discrepancy.
Alabama Learning Exchange
Alex: Students Only! No Teachers Aloud
The students will be introduced to area and perimeter. The teacher will pose a real-life situation in which the students will have a chance to explore an actual section outside to determine the area and perimeter of a set location.
