Come look at trigonometry from a different angle. To begin a simple activity, scholars view a video of someone using a clinometer to find the angle of elevation to the top of a building. They then use a diagram that shows the building's height to determine how far away the observer is from the building.

Instructional Ideas

• If possible, have the class do a similar activity outside using a tall building or tree
  

Classroom Considerations

• Learners should be familiar with trigonometry
• Pupils may not know what a clinometer does
  

Pros

• Use of a video makes the concept real
  

Cons

• Only presents one problem in the task
