Mensuration

  1. 1. Use vocabulary for 3D shapes: vertex, edge, face.
  2. 2. Classify 3D shapes and identify their properties.
  3. 3. Draw and interpret nets of 3D solids.
  4. 4. Calculate the volume of prisms (including cylinders).
  5. 5. Calculate the volume of pyramids and cones (V = ⅓ × base area × height).
  6. 6. Calculate the volume of a sphere (V = ⁴⁄₃ π r³).
  7. 7. Calculate the surface area of prisms and cylinders.
  8. 8. Calculate the surface area of a sphere (SA = 4πr²).
  9. 9. Convert between units of capacity, area and volume.
  10. 10. Substitute values into mensuration formulae.
  11. 11. Rearrange mensuration formulae to make a different variable the subject.
