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 item(s)
    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.
