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!
