# KS2 Maths Lessons: Year 3 Maths

## Challenge level ⭐⭐

(designed for children with prior knowledge of the Year 3 and Year 4 programme of study)

**Learning Objective**

We are learning how to identify whether angles are greater than or less than a right angle.

**Context:** the natural world

## Clip Description

In nature, angles are present everywhere.

They can be seen between the tentacles of a snail and the veins of a leaf.

In this fascinating clip, we are transported to the Alladale Wilderness Reserve in the Scottish highlands. You’ll see colourful hills and glistening rivers that are teeming with wildlife. **As you watch the clip, make a mental note of the different places that angles can be seen.**

## Quick Whiteboard Challenge

In this lesson, we will be introduced to right-angles. A right angle is a special type of angle that has a size of 90 degrees.

**Can you think of a number sentence that equals 90, which no one else in the class will have thought of? **
