  • Angles are created when two meet in a corner.
  • A polygon is a closed 2D shapes with 3 or more sides. It comes from the Greek words poly (many) and gon (angle).

Rotation 1: Using Geo-boards students create various sizes of angles.
  • Right angles
  • Small angles – Acute
  • Large angles – Obtuse

Rotation 2 Activity sheet: Creating and shading in clock faces to create :
  • Right angles
  • Small angles – Acute
  • Large angles – Obtuse

Rotation 3 Activity sheet: labelling and locating angles
  • Right angles
  • Small angles – Acute
  • Large angles – Obtuse

Rotation 4: Playing and exploring protractors, large and small

  • Emphasis is for students to be made aware of how to measure angles using protractors. There are two ends, left and right, each with a zero as starting point.
  • Students to draw protractors in there maths books


Measurement activity is angles
L.O
I am learning to identify and make angles.

I am learning to work out different types of angles.



Today we will explore angles in the environment and how to use a protractor. Now it is time to focus on what we can estimate and see in real life!

We are going to begin with this website:
