Summary: 3 Credit Internal Assessment

Constructions, loci, bearings, vectors, grid references, 3-D shapes, sections of 3D shapes, isometric drawing, views of 3-D shapes, nets

  • Construct and describe simple loci.
  • Interpret points and lines on co-ordinate planes, including scales and bearings on maps.
  • Create accurate nets for simple polyhedra and connect three dimensional solids with different two dimensional representations.
  • Use a co-ordinate plane or map to show points in common and areas contained by two or more loci.
