Topic # 21 Investigating Area and Volume

Learning Expectations:

* Relate the area of a polygon to the number of square that cover it with no gaps or overlaps. Area is the amount of surface in a region or enclosed within a boundary.

Area is usually measured in square units, such as square feet or square centimeters.

* Measure volume. Explore volume as “filling space.” Solve problems with volume.

Volume is the amount of space inside a three-dimensional shape or occupied by a solid. Volume is measured in cubic units, such as cubic feet or cubic centimeters.
