Some of you may remember the pi-rap-video suggested last year. It was the creation of Nathan Shields, a mathematics teacher at Fort Vancouver High School (WA), and a former student of mine.
Nathan has now put together his own creative web site, called 10-Minute Math. Its focus seems to be to provide short videos that explore creative sides of mathematics, with a few tangential elements.
Some diverse things of interest to secondary mathematics teacher that are currently available on the web site:
And the content continues to grow gradually.
- The video A Mandelbrot the Size of the Known Universe
- A teacher-made video about teaching slope
- Instructions for boosting the processing speed of a TI-86 by a factor of 3
- A dynamically-controlled millipede
- A visual connection of the Golden Spiral to the arrangement of the seeds on a sunflower
- Frog-Jump game that can be explored using a mathematical strategy
- Instructions for building an inexpensive document camera for use with an LCD projector
- A classroom timer that could prove useful in certain situations
Well done, Nathan!
