PROCEDURAL
Mathematics›Geometry|Ages 5—6|ID: mt_XjwUlmxdCT

Compose simple shapes to form larger shapes (e.g. two triangles make a rectangle)

Mastery Evidence

  • Join two triangles to make a rectangle or larger triangle
  • Use pattern blocks to fill a hexagon outline
  • Create a picture or design by combining basic shapes

Assessment Prompt

“Can [child] fit smaller shapes together to make bigger ones — like combining two triangles to make a rectangle?”

  • 2-D shapes hard

    Composing shapes requires recognising the component shapes

  • 3-D shapes (age 5+) soft

    Composing shapes benefits from understanding shape attributes to know how pieces fit together

    • 2-D shapes hard

      Analysing and comparing shapes requires being able to name them first

    • 3-D shapes hard

      Analysing 3-D shapes requires recognising and naming them
