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).
Estimate and use U.S. Customary and metric units to measure the distance around a polygon with no more than six sides to determine the perimeter. (a)
Determine the area of a given surface by estimating and then counting the number of square units needed to cover the surface. (b)
Estimate and measure the weight/mass of objects in both U.S. Customary and metric units (ounce, pound, gram, or kilogram) to the nearest appropriate measure, using a variety of measuring instruments. (b)
measure the distance around a polygon in order to determine its perimeter using U.S. Customary and metric units; and
Perimeter and area should always be labeled with the appropriate unit of measure.
estimate and measure liquid volume and describe the results in U.S. Customary units; and
length to the nearest inch; and
Estimate and then measure the length of various line segments and objects to the nearest inch using a ruler. (a)
Estimate and then measure the weight of objects to the nearest pound using a scale. (b)
