1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89… to infinity and beyond!
It’s not a phone number. It’s not a secret code. It’s not the winning lottery ticket. Nope. It’s the Fibonacci sequence.
We explored the Fibonacci sequence by making Ann McCallum’s “Fibonacci Snack Sticks” from Eat Your Math Homework. We selected a number of bite-sized morsels (gummy bears, strawberries, blackberries) and threaded them onto skewers according to the sequence. For example Cooper chose one gummy bear, one blackberry, two strawberries, three gummy bears, five strawberries, eight gummy bears for his skewer. (Side note: Mmmmmm, gummy bears.) This activity sparked a discussion about the sequence, where you can see it, how find the next number and more.
We turned to McCallum’s book for answers. You may be wondering, as we did, “Who is this famous Fibonacci?” Well, he was an Italian mathematician circa 1170. Studying rabbit pairs and their mating patterns, he devised his sequence of numbers to explain how many pairs of rabbits he would have each month. But you don’t have to breed rabbits to get the sequence. To get the next number, you simply add the two previous numbers together.
This sequence shows up repeatedly in nature, in shell patterns, petals and more. “Nature by Numbers” is a wonderful video showing the pattern’s prevalence.
But I digress…You’ll find Fibonacci fun and more in Ann McCallum’s Eat Your Math Homework: Recipes for Hungry Minds, which combines hands-on math with yummy food. Just wait until we get to Fraction Chips. Your mouth will water.
