Instructional Ideas

• Create practice problems that are similar to the guided practice problems

Classroom Considerations

• Requires prior knowledge of rectangular coordinates, sine, cosine, and tangent
• Lesson best fits as an introduction to polar coordinates

• This resource is only available on an unencrypted HTTP website.It should be fine for general use, but don’t use it to share any personally identifiable information

Pros

• Includes a concept video and three practice problem videos
• Walks through each problem step by step with easy-to-read diagrams

Cons

• Video is not engaging and may not hold pupils' attention
