CONCEPTUAL

Identify and describe properties of 3-D shapes including the number of edges, vertices, and faces

Mastery Evidence

  • Count the edges, vertices, and faces of common 3-D shapes
  • Use the terms edge, vertex (vertices), and face correctly
  • Describe a 3-D shape by its properties (e.g. a cube has 6 faces, 12 edges, 8 vertices)

Assessment Prompt

“Can [child] count the faces, edges, and vertices of a 3-D shape like a cube or triangular prism?”

Mathematics · Key Stage 1

Prerequisites3

Show full prerequisite tree
  • 3-D shapes hard

    Describing 3-D properties (edges, vertices, faces) requires knowing the shapes first

  • Nets of 3-D Shapes soft

    Counting edges, vertices, and faces is reinforced by analysing nets where each face is visible as a separate 2-D shape

  • 3-D shapes (age 5+) hard

    Formal property description extends informal analysis of shapes

    • 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
