Learn that area is a measure of how much surface is covered. Explore the relationship between the size of the unit used and the resulting measurement. Find the area of irregular shapes by counting squares or subdividing the figure into sections. Lear...n how to approximate the area more accurately by using smaller and smaller units. Relate this counting approach to the standard area formulas for triangles, trapezoids, and parallelograms.

Review appropriate notation for angle measurement, and describe angles
in terms of the amount of turn. Use reasoning to determine the measures
of angles in polygons based on the idea that there are 360 degrees in a
complete turn. Learn about the r...elationships among angles within
shapes, and generalize a formula for finding the sum of the angles in
any n-gon. Use activities based on GeoLogo to explore the differences
among interior, exterior, and central angles.
