Instructional Ideas

• Take learners outside to apply trigonometry to determine the height of a tree, flagpole, etc.

Classroom Considerations

• Video assumes viewers know how to construct a clinometer from a protractor
• Learners must have previous experience with trig applications

• This video is hosted on YouTube

Pros

• The process of using trigonometry is shown step by step

Cons

• Includes only one example
• Uses only a tangent function (no other trigonometry applications)
