Unit focus

  • Students estimate from 90°, 180° and 360° benchmarks, align a protractor correctly, select the correct scale and classify measured angles by name.
  • Use this routine: Represent → Reason → Calculate → Interpret → Verify.
  • Watch for vertex not at centre: The centre mark must match the angle vertex.
