Instructional Ideas

  • Use this short, interesting, math-in-real-life video to kick off a lesson on the geometric mean or a lesson on comparing the use of two statistical values like the average verses geometric mean
  • Build your own lesson that has learners collaboratively creating their own online dating algorithm and trying it out at school
  • A fun experiment might be to have learners compare and contrast two different algorithms using data collected from happily married couples

 

Classroom Considerations

  • Consider people’s privacy or anonymity as learners collect data

Pros

  • Presents math in a fun, personal light
  • Animated and nicely presented
  • Interesting and motivating

Cons

  • None
