Instructional Ideas

• Provide learners with a graphic organizer to record new vocabulary and examples
• Begin with a review of unit conversions to relate to degree-to-radian conversions

Classroom Considerations

• Pupils should be familiar with the graph of the sine and cosine functions and the unit circle
• The ninth lesson in a 19-part series

Pros

• Includes detailed teacher notes to use throughout the lesson
• Provides opening and closing activities complete with answer keys

Cons

• None
