Angle Scavenger Hunt –  Have your students explore the classroom or playground to find real-life examples of the six types of angles from the presentation: acute, right, obtuse, straight, reflex and revolution. Allow the students to use a device to take photographs of the angles they find, or to draw and label sketches of the angles they discover in their workbooks.
2. Angle Artworks – Have the students create a collage or geometric artwork using the six different types of angles. Students can colour-code their work according to angle type, enabling them to not only produce a piece of artwork but to demonstrate their knowledge, too!
3. Design a Room – Challenge students to design their dream room using geometric shapes and various angle types. Students plan where to place furniture within the room while including angles that meet certain criteria. Teach Starter’s Design a Room Maths Investigation is the perfect resource should you choose to explore this activity with your class!
