Measuring the Perimeter and Area of Polygons
Section 12.2
| Activity Name | Activity Description |
|---|---|
| Area Explorer | Students are shown shapes on a grid after setting the perimeter and asked to calculate areas of the shapes. |
| Shape Explorer | The applet creates an irregular shape on a grid. Students determine area and perimeter of the given shape and check their answers with input to the applet. |
| Triangle Explorer | The applet creates a right triangle on a grid. Students determine area of the triangle and check their answers with input to the applet. The applet also supplies a 'hint' function that outlines a rectangle containing the original triangle. |
| Perimeter Explorer | Students are shown shapes on a grid after setting the area and asked to calculate perimeters of the shapes. |
