Fibonacci day is coming up this Saturday, November 23rd. What or who exactly is Fibonacci? It's a mathematical sequence named after a man named Fibonacci, hence the name "Fibonacci Sequence".
The full sequence goes 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, and so on. You start with 1 and add it to another 1. Then you add the first two numbers to get the third number, the second and third to get the fourth number, and it continues from there.
We have some cool books that explain more, so be sure to check them out and read them with your class. Fibonacci is not complicated, but it sure looks that way!
Starting with a biography of the man who the sequence is named for, Blockhead: The Life of Fibonacci by Joseph D'Agnese, we see that not everyone thought Leonardo Fibonacci was very smart. In fact, teachers called him lazy! The numbers that made him happy were just a pattern waiting to be discovered. And he is now considered one of the greatest Western mathematicians of all time!
Another book, Eat Your Math Homework: Recipes for Hungry Minds by Ann McCallum, shows how math paired with cooking is a perfect match for curious minds! Fibonacci snack sticks sound delicious, don't they?!
Here are some awesome videos that explain Fibonacci numbers in much greater detail:
