The student will estimate and a) measure the distance around a polygon in order to determine its perimeter using U.S. Customary and metric units; and b) count the number of square units needed to cover a given surface in order to determine its area.
Understand how to determine the perimeter by counting the number of units around a polygon.
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.
Opportunities to explore the concepts of perimeter and area should involve hands-on experiences (e.g., placing toothpicks (units) around a polygon and counting the number of toothpicks to determine its perimeter and filling or covering a polygon with tiles (square units) and counting the tiles to determine its area).
