# Angles

Part of:

##### Lesson overview

In this lesson students will develop their knowledge of angles including right angles. Students will understand how many right angles are in a full turn, as well as identifying whether angles are greater or less than a right angle.

##### Learning outcomes
• Identify right angles
• Recognise that two right angles make a half-turn, three make three quarters of a turn and four a complete turn
• Identify whether angles are greater than or less than a right angle
• Identify, measure and name a range of angles

Expedition Prep Checklist

Explore the expedition and locate points of interest.

##### Lesson steps
1. Expedition one (10 mins)
In pairs students explore ‘Svartifoss Waterfall’. One directs their partner around Svaritfoss Waterfall using key vocab such as ‘Face the water falling from the waterfall, turn 90 degrees. What different angles can you see? Is it less than or greater than 90 degrees? What do you see?’ Record on the Student Sheet in the Lesson resources section. Students to then swap with partner and tick if correct.
2. Expedition two (10 mins)
They should come up with similar questions to the last destination for another pair. Remind them to include a starting position, a turn, a direction, greater than / less than and instructions. These could be multi-step for challenge.
3. Expedition three (10 mins)
Students to complete the same for the Blue Lagoon Waterfall.
4. Activity (30 mins)
Students draw 90, 180 and 360, acute, obtuse and right angles.
5. Extension
Students plan a town with only acute, obtuse and right-angled blocks including a town square, park, town hall, police station, and a supermarket. Students write directions between the places above.
