Grade 4 - Shape and Space

Standard 4.SS.3 - Find the area of a shape using unit squares.

Included Skills:

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 cm² or m²
estimating area by using referents for cm² or m²
determining and recording area (cm² or m²)
constructing different rectangles for a given area (cm2 or m2) in order to demonstrate that many different rectangles may have the same area.

Achievement Indicators
Students who have achieved this outcome(s) should be able to:
- Describe area as the measure of surface recorded in square units.
- Identify and explain why the square is the most efficient unit for measuring area.
- Provide a referent for a square centimetre and explain the choice.
- Provide a referent for a square metre and explain the choice.
- Determine which standard square unit is represented by a given referent.
- Estimate the area of a given 2-D shape using personal referents.
- Determine the area of a regular 2-D shape and explain the strategy.
- Determine the area of an irregular 2-D shape and explain the strategy.
- Construct a rectangle for a given area.
- Demonstrate that many rectangles are possible for a given area by drawing at least two different rectangles for the same given area.
