One of the more interesting requests I receive at my library’s reference desk comes from parents seeking math books for their kids. Generally speaking, they don’t want math textbooks or worksheets of math problems. No, they want books in a picture book format that incorporate math in some original manner. Now it is fortunate that there are a slew of such books out there. You can find them in any good children’s library if you know where to look and with the right teacher or parent, such books can make concepts like fractions or division or subtraction make perfect sense. Fibonacci numbers are a little trickier. Unlike addition or multiplication they are difficult to show to kids as having practical applications in real life. You could discuss how Fibonacci numbers apply to music, but that’s still tricky territory. Nature, however, is a natural complement. Kids understand flowers. Kids can understand duplicating numbers. Put the two together and you’ve the newest picture book format math book to add to your shelves. It does contain a couple difficult concepts, but with the right grown-up by their side, there’s very little in Growing Patterns: Fibonacci Numbers in Nature that a child won’t be able to figure out on their own.
Take a look at these flowers and count the petals you see. One. Two. Three. Five. Eight. Notice anything? These petal numbers add on to one another. One plus two equals three. Two plus three equals five. These numbers are called Fibonacci numbers, and what’s crazy is that as they go they keep showing up in nature and it’s not just in flowers either. If you count spirals on pinecones or sunflowers or pineapples, no matter how you look at them they equal one of these numbers. With brilliant bright photography and simple words, Sarah and Richard Campbell make a math concept understandable. A section on “More About Fibonacci Numbers” and a Glossary of terms appear at the end.
It may sound as if this is a fairly simple and straightforward concept, but how do you write an entire book about duplicating numbers found in nature for youngsters? The Campbells have opted for starting out easy and getting slowly more complicated as the book goes on. So at the start the child reader is handed a really easy idea. They look at pictures and count the petals. By the time they get to the eight petals on the cosmos they learn about doubling the numbers and we see the same flowers all over again. Then the numbers get higher. The ideas get harder. It’s clear that some adult help may be needed to explain along the way.
I suppose the real question here is whether or not kids are gonna get all the concepts the book is throwing out. At the start it’s pretty clear but when it starts getting into counting the number of spirals, that’s when things begin to get wonky. You have to realize that spirals on pinecones and sunflowers and pineapples can go a variety of different ways. What would be fun is if grown-ups turn it into a game. What if you bought a pineapple and had the kids identify the spirals and then count them? That’s pretty cool. Of course then you start getting into the golden spiral concept and that gets kind of complicated. And, of course, if your child attempts to understand The Golden Ratio explanation at the end of the title, sign that kid up f
Thanks Betsy. As usual, your review is chock full of great extras that I am going to bookmark. I picked this little baby up for my middle school library. The seventh grade math and art teachers collaborate on a Fibonacci project.
I also find it funny how many coincidences happen in my reading. I was lucky to read Sugar and Ice as well! I love how Kate Messner weaves instructional units so naturally into her stories. Last year it was Norse mythology – Gaiman’s Odd and the Frost Giant, Libba Bray’s Going Bovine and Eoin Colfer’s sequel to Douglas Adams’ Hitchhiker’s Guide series, And Another Thing. After reading all three of these within a month of each other, I had an itch to delve into Norse mythology.
Happy reading.
