Grade 3 - Measurement and Data
Standard 3.MD.1.5 - Find the perimeter of a complex figure.
Included Skills: Geometry
Students will be expected to demonstrate an understanding of perimeter of regular, irregular, and composite shapes by • estimating perimeter using referents for centimetre or metre (cm, m) • measuring and recording perimeter (cm, m) • create different shapes for a given perimeter (cm, m) to demonstrate that many shapes are possible for a perimeter • Performance Indicators - M05.01 Measure and record the perimeter of a given regular shape and explain the strategy used. - M05.02 Measure and record the perimeter of a given irregular or composite shape and explain the strategy used. - M05.03 Construct a shape for a given perimeter (cm, m). - M05.04 Construct or draw more than one shape for the same given perimeter. - M05.05 Estimate the perimeter of a given shape (cm, m) using personal referents.
