Fibonacci cube

Hey kiddo! Have you heard of the Fibonacci Cube? It's a cool math concept that uses numbers from the Fibonacci sequence to create a cube!

First, let's talk about the Fibonacci sequence. It's a series of numbers where each number is the sum of the two preceding ones. So it goes like this: 0, 1, 1, 2, 3, 5, 8, 13, 21, and so on.

Now, imagine we have a cube made up of smaller cubes, sort of like a Rubik's cube. The Fibonacci Cube is when the number of small cubes in each layer follows the Fibonacci sequence. So the first layer has 1 cube, the second layer has 1 cube, the third layer has 2 cubes, the fourth layer has 3 cubes, the fifth layer has 5 cubes, and so on.

If we counted all the small cubes in the Fibonacci Cube, we would get numbers from the Fibonacci sequence! Pretty neat, huh?

This is just one way that math can be used to create interesting patterns and shapes. Now, let's go play with some blocks and build our own Fibonacci Cubes!
