Grade 3 - Measurement and Data

Standard 3.MD.1.5 - Given the perimeter of a figure, calculate the missing side.

Included Skills:

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.
