Standards Icon Benchmark #:MA.1.G.3.2

  • General Information
    • Benchmark Number: MA.1.G.3.2
      Benchmark Description: Compose and decompose plane and solid figures, including making predictions about them, to build an understanding of part-whole relationships and properties of shapes.


      Subject Area: Mathematics
      Grade Level: 1
      Body of Knowledge: Geometry
      Big Idea: BIG IDEA 3 - Compose and decompose two-dimensional and three-dimensional geometric shapes.
      Date Adopted or Revised: 09/07
      Date of Last Rating: 06/07
      Cognitive Complexity: High   -  What does this mean?
      Status: State Board Approved
      Remarks/Examples: Example of composing: The student puts two congruent isosceles triangles together to make a rhombus.

      Students can decorate necklaces by composing triangles (or other shapes) and find number of triangles or rhombuses needed for different necklaces with different lengths.


      Example of decomposing: The student notices that a regular hexagon can be decomposed into two trapezoids or six triangles.
