Grade 4 - Shape and Space

Standard 4.SS.2 - Find the area of a rectangle using its side lengths.

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.
Describe area as the measure of surface recorded in square units.
Identify and explain why the square is a 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 referent.
Estimate the area of a 2-D shape using personal referents.
Determine the area of a regular 2-D shape and explain the strategy used.
Determine the area of an irregular 2-D shape and explain the strategy used.
Construct a rectangle with a given area.
Illustrate, and verify, how more than one rectangle is possible for a given area by drawing at least two different rectangles with that area (e.g., identifying the dimensions of each rectangle drawn, or superimpose the rectangles on each other).
