This site provides multi-leveled practice with calculating the area of random shapes. The applet allows the creation of random shapes to be used in finding area. Options allow for changing the perimeter, displaying the rectangular outline, scored or not scored, and the amount of units to be included. The learner area of the site explains the concept of area and includes charts comparing metric to standard units as well as an explanation on how to convert square feet into square meters. The instructor area includes links to standards and some textbooks, information needed for classroom use, links to similar resources, and a link to downloadable exploration questions.
In the Classroom
Use this site as an anticipatory set or "activator" to introduce a unit or lesson on area on a projector or interactive whiteboard. Then have students complete the exploration questions on their own or with a partner. Use this site on a projector or interactive whiteboard to discuss and informally assess prior knowledge as you start your study of area. Make a link on classroom computers to use as a center activity.
At Home
Use this site with your student learning about area, perimeter, and angles.
