Benchmark Number: MA.4.G.3.1
Benchmark Description: Describe and determine area as the number of same-sized units that cover a region in the plane, recognizing that a unit square is the standard unit for measuring area.
Subject Area: Mathematics  
Grade Level: 4  
Body of Knowledge: Geometry  
Big Idea: BIG IDEA 3 - Develop an understanding of area and determine the area of two-dimensional shapes.  
Date Adopted or Revised: 09/07  
Date of Last Rating: 06/07  
Cognitive Complexity: Moderate  -  What does this mean?  
Status: State Board Approved  
Remarks/Examples: Geoboards, tiles, and grid paper provide helpful contexts for this exploration. The focus is on countable units rather than multiplying dimensions.

Reporting Category: Geometry and Measurement
Item Type(s):
This benchmark will be assessed using: MC items.
At Grade 4, this benchmark will be assessed using MC items.
Clarification: Students will determine the area of a figure or a region on a plane by using countable units rather than multiplying dimensions.
Content Limits: Items may include estimating areas of irregular geometric shapes, such as a figure in the shape of a pond, a mitten, a foot, the sole of a shoe, or a solid letter D.

Items should include countable units that estimate to a whole unit or half unit.

Items may use only a one-to-one scale.
Stimulus Attributes: Shapes must be shown on a grid (or a gridlike graphic, such as geoboards or tiles); however, grid lines need not extend through the shape.

Items may be set in either a real-world or mathematical context.
Prior Knowledge: Items may require the student to apply mathematical knowledge described in the Standards from lower grades. This benchmark requires prerequisite knowledge from MA.4.A.2.4.
