Area and Perimeter

Students will need to have already been introduced to area and perimeter and be familiar with how to find each of these.
Day 1 - After passing out geoboards, rubber bands, and digital cameras, students will be instructed to create at least 5 different polygons on their board. After each polygon has been created, students will take a picture of the image using their cameras.
Day 2 - Students will upload their geoboard images to the computer, and transfer them into Keynote. Students will create a slide for each image, and will add a heading to each slide which states the area and perimeter of the image for that slide.
Day 3 - Students will present their slide shows and will demonstrate how they arrived at the area and perimeter for each image.

| Students could be grouped according to type of polygons. One group could upload all the squares and find the area and perimeter for the squares, while another group would be working with the pentagons. |
| Follow-Up |
| Students can move from finding the area and perimeter of polygons made on geoboards, to taking pictures of items around the school, such as their desk, the door, floor tiles, and finding the area and perimeter of these items. They would need to apply the formulas for area and perimeter to find these for the new items since they will not have the grid of the geoboard. |
