Fibo-Nachos, Anyone? Have Some Tasty Fun Teaching the Fibonacci Sequence

Posted 11/23/2018 by Ellen Fishpaw (@ellenfishpaw)

It’s Fibonacci Day, and we’re celebrating this mathematical milestone by whipping up something near and dear to our Texas roots — nachos, or Fibo-nachos. (Too cheesy? Nah.)

November 23 is known as Fibonacci Day because when the date is written in the mm/dd format (11/23), the digits in the date form the beginning of the Fibonacci sequence: 1, 1, 2, 3.

We don’t have to tell you that the Fibonacci sequence is a sequence of numbers, defined by a linear recurrence equation, where a number is the sum of the two numbers before it. For example: 1, 1, 2, 3 ... is the Fibonacci sequence. Here, 2 is the sum of the two numbers before it (1+1). Similarly, 3 is the sum of the two numbers before it (1+2). There are many fascinating things about the sequence. Perhaps most interesting is the fact that the ratio of subsequent Fibonacci numbers converges on the golden ratio, phi (Ø = 1.618…), as the number of terms approaches infinity.

Click on the short video below that shares our favorite recipe for phi-lling Fibo-nachos. (Really loving that cheese, huh?) By the time you’re done, you’ll learn how to make golden, rectangle tortilla chips and use the Fibonacci sequence to build delicious Fibo-nachos. As you may expect, we’ve made certain that our Fibo-nachos include the golden ratio of chips to cheese. 

Be sure and try our recipe with your students for a fun and tasty way to teach the Fibonacci sequence.

  • 1 small onion, diced
  • 1 avocado, sliced
  • 2 cups oil
  • 3 tablespoons salsa
  • 5 jalapeños, sliced
  • 8 ounces shredded cheese
  • 13 corn tortillas

Happy Fibo-nacho Day!
