Other Examples:

  • To break apart a square, the child may say that a cut needs to be made from angle to angle to make two right triangles.
  • Given hexagons, can break one or more apart to make shapes such as trapezoids and triangles.

Help your student become a(n) Shape Decomposer with Imagery

These activities ask children to plan a decomposition, by describing or drawing it, so they have to imagine the decomposition before they carry it out.
