### A Picture Book and…Fibonacci?

I may have just broken a code.

A math sequence. The fibonacci sequence (1,1,2,3,5,8,13,21,34,55…)

In a picture book of all places!

Disclaimer: my neurologist did say my left parietal lobe could have trouble with math after surgery.

To that I say…psshh. Lame.

Disclaimer #2: I was never very good at math.

The book is Jack, by Tomie DePaola. It's a beautifully illustrated book, seemingly not at all about math. Interesting! Let's take a look...

Jack lives with his grandfather out in the country. One day, he decides to try out city life. His grandfather is very supportive and offers Jack advice to seek help from the king. Along the way, Jack makes an assortment of friends.

So Jack (our #1 hero) sets out for the city, leaving his grandfather (1).

On the way, he meets a chick (nice pun, DePaola).

Jack + chick = 2

Then Jack meets a duck:

Jack + chick + duck = 3

Next Jack meets a goose and a dog:

Jack + chick + duck + goose + dog = 5

Then a frog, a pig, and a cow:

Jack + chick + duck + goose + dog +frog + pig + cow = 8

Next, Jack meets a cat, a sheep, a horse, and an owl:

Jack + chick + duck + goose + dog +frog + pig + cow + cat + sheep + horse + owl = 12. I know, I know. The next Fibonacci number should be 13. But what the text leaves out, the illustration makes clear: + crow. The crow joins the group for the rest of the story and we now have 13.

The other characters are quiet observers in the scenery. They include two doves on the dedication, a worm, ants, mice, spider, nuns, Jack & Jill, Humpty Dumpty, a guard, king, queen, etc.

I wonder if they make 21? 34?

Don't forget that crow!

I'll leave that for you to decide. My brain needs some rest. This is where too much time on my hands has led me. But it was worth it. Whether or not my math holds true, this story illustrates how to be inclusive...and the beautiful outcome that builds from there.

Have fun delving into this fun, beautiful book!
