Hank introduces us to the most beautiful numbers in nature - the Fibonacci sequence.

Piano musical piece created by assigning numbers in the Fibonacci Sequence to the E major scale. This is what the sequence sounds like as music

The Fibonacci sequence is a series of numbers in which a given number is the addition of the two numbers before it. So, if you start with 0, the next number will be 1, followed by 1, followed by 2, followed by 3 and so on.

Students will learn about patterns in groups of numbers.
