Grade 4 - Measurement and Data

Standard 4.MD.1.3 - Compare two figures and find which has the greater perimeter or area.

Included Skills:

Students will be expected to demonstrate an understanding of area of regular and irregular 2-D shapes by

• recognizing that area is measured in square units

• selecting and justifying referents for the units square centimetre (cmÂ²) or square metre (mÂ²)

• estimating area using referents for cmÂ² or mÂ²

• determining and recording area (cmÂ² or mÂ²)

• constructing different rectangles for a given area (cmÂ² or mÂ²) in order to demonstrate that many different rectangles may have the same area

• Performance Indicators

- M03.01 Describe area as the measure of surface recorded in square units.

- M03.02 Identify and explain why the square is the most efficient unit for measuring area.

- M03.03 Provide a referent for a square centimetre, and explain the choice.

- M03.04 Provide a referent for a square metre, and explain the choice.

- M03.05 Determine which standard square unit is represented by a given referent.

- M03.06 Estimate the area of a given 2-D shape using personal referents.

- M03.07 Determine the area of a regular 2-D shape, and explain the strategy.

- M03.08 Determine the area of an irregular 2-D shape, and explain the strategy.

- M03.09 Construct a rectangle for a given area.

- M03.10 Demonstrate that many rectangles are possible for a given area by drawing at least two different rectangles for the same given area.
