Standards Icon Benchmark #:MA.4.G.3.1

  • General Information
    • 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
      Assessed? Assessed
      Remarks/Examples: Geoboards, tiles, and grid paper provide helpful contexts for this exploration. The focus is on countable units rather than multiplying dimensions.

  • Test Item Specifications
    • 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.
