Instructional Ideas

• Provide the class with a timeline on the history of pi
  

Classroom Considerations

• Pupils should have familiarity with circumference
• Learners must also understand infinite series
  

• This video is hosted on YouTube

Pros

• Diagrams help illustrate Archimedes' method for determining pi

Cons

• Mnemonic does not correctly give the digits of pi
  
• Narration is split between two speakers, but switching back-and-forth between the speakers results in a lack of continuity
