Amazing Angles

Preparation

Reminders

• All hardware has been charged and sanitised.
• Student Devices have the most recent updated version of CoSpaces installed.

Tasks

• The following slide deck Teaching Deck – Year 3 Amazing Angles has been checked and the teacher has accessibility.
• Students have been divided into pairs or groups and names are written on Slide 6.
• A copy of the Scavenger Hunt Template and Merge Cube Record Template have been printed for students to complete.

Learning Sequence

Introduction

• View Right Angles as a class and discuss:
• • • What objects did the video show to have right angles?
    • How do you know if an angle is a right angle?
    • Can you find something that doesn’t have a right angle?
• Introduce the focus of this lesson to students. Tell them that they will be learning more about right angles by viewing an AR experience using a Merge Cube, and going on an angle scavenger hunt. 

Development

• Revise the three characteristics of a right angle using Slide 3 of the Teaching Deck – Year 3 Amazing Angles
• Using Slides 4 and 5 of the Teaching Deck – Year 3 Amazing Angles, discuss how we can compare other angles by identifying whether they are greater or smaller than a right angle.
  
• Split the class into two groups, write their names on the table on Slide 6 of the Teaching Deck – Year 3 Amazing Angles and explain the following two tasks to students using Slide 7.
• AR CoSpaces Task:  with a device from the AR/VR kit, students view the Amazing Angles Merge Cube using the CoSpaces app. In this experience, students examine a series of objects to identify right angles, and angles that are greater/smaller. Students need to tap on the angles they see, and correctly identify whether it is a right angle, or greater / smaller. 

Optional: students record the angles that they find using the Merge Cube Record Template

• Right Angle Scavenger Hunt: students conduct a scavenger hunt around their classroom and surrounding areas to find as many right angles as possible. Students also need to find angles that are greater / smaller than right angles. They keep track of what they find using the Scavenger Hunt Template. Students can work in pairs or individually.
• After students have worked on their first activity for 10-15 minutes, swap the groups over.
• Ensure students return the devices to the AR/VR kit when finished.

Conclusion

• Ask students to pair up with another group and take turns sharing which objects they found during their Scavenger Hunt.
• Discuss the following as a class using Slide 5
  • Did your groups find any of the same objects?
  • Did anybody find angles that are greater than / smaller than a right angle?
