Polar Graphs

The world of graphing polar graphs is filled with beautiful curves and patterns once a young mathematician masters a few basic techniques. This comprehensive resource covers many of these techniques and resulting shapes, from the basic circle through elaborate rose curves and beyond. Instruction summaries and many worked examples through the presentation and notes make this a fabulous lesson for the class to have to look back on as they grow in mathematical sophistication.

Instructional Ideas

  • Consider using as a turn-key plan (presentation, notes, homework and answer key) for a highly-qualified sub
  • For interested learners, follow this lesson with research into rose curves and other polar graphs in nature
  • Have pairs of learners create problems based on those presented for one another, following different shape rules
  • Work with an art teacher to create beautiful murals or posters using polar graphing techniques
Classroom Considerations

  • Class notes, homework sheet, and answer key to match the main resource presentation are all attached under additional resources
  • Presentation PDF would make a great interactive whiteboard presentation, with steps and solutions revealed as the problems progress
Pros

  • Polar graphs are built from the most basic through more complex patterns
  • Graphs are compared and contrasted throughout the notes, making the fine distinctions between different styles
  • Homework sheet follows note examples closely, without repeating problems
Cons

  • None
