Students will take photos of polygons in the real world, find their perimeter, and present their photos and findings in an Adobe Spark creation.

In this Cyberchase video segment, the CyberSquad learns what happens to the area of a rectangle when the shape enclosed by the perimeter changes.

In this investigation students work systematically and keep organized records as they explore forming triangles from unit sticks. Learners look for patterns and trends in the number of triangles possible with a given integer perimeter. Ideas for implementation, extension and support are included along with a printable sheet of the problem.

This activity provides students with an opportunity to calculate area and perimeter of rectangles in order to determine the pricing system of objects with given costs (in British Pounds). The resource includes the problem, tips on getting started, a teacher resource page, and a printable student page.
