Today I brought to math class:

  • a pineapple
  • a stalk of broccoli
  • a picture of the galaxy in a spiral
  • three oak leaves
  • a bough from a fir tree
  • a ruler to measure the knuckle lengths on our hands

Why?

We were searching for the Fibonacci sequence.

The 8th grade is currently working on Algebra 1, which includes sequences and linear equations. Since it is the end of the unit, I thought it would be cool to find a connection to the real world. We graphed the Fibonacci sequence and practiced finding equations from the sequence. Finally, we looked at the spiral the sequence can make in produce and leaves I brought in.

Cleveland Art has a fantastic lesson on how this relates to art and rectangles we see today with candy bars, credit cards, and more. Cleveland Art: Fibonacci Sequence Slideshow
