3.10

The student will

a) measure the distance around a polygon in order to determine perimeter; and

b) count the number of square units needed to cover a given surface in order to determine area.

Measure each side of a variety of polygons and add the measures of the sides to determine the perimeter of each polygon.
Determine the area of a given surface by estimating and then counting the number of square units needed to cover the surface.
