Idea Summary: Use Google Maps satelite images (and their scales) to teach perimeter and area and their real life uses.
Description:
This unit takes about 10 days to complete. Project the sateliteimage of the school or a nearby area onto a whiteboard. Put twostudents (a measurer and a calculator) at the board with the taskof figuring out the area and perimeter of the school building.Student measurer should be supplied with a regular ruler. The twostudents at the board have to wait for other students to instructthem before they make a move. The students will soon discover thatthey need the map scale to convert map measures to actual measures.They will also learn that the conversion factor they use forsingle-dimensional measures has to be doubled for two-dimensionalmeasures.

After teaching the perimeter and area formulas using examples fromGoogle Maps satelite images for three days, a unit project isintroduced in the Mac lab. The project is described in myattachment
