Growing Patterns:Fibonacci Numbers in Nature by Sarah C. Campbell
There’s a number sequence, a pattern, that mathematicians call Fibonacci numbers. Each number is the sum of the two numbers that come before it: 1, 1, 2, 3, 5, 8, 13…and so on. So what? Well, it happens that this pattern shows up in the strangest places throughout nature. In the petals on a flower, the bracts on a pinecone, the skin of a pineapple, and the shell of a nautilus. Who knew that nature and math were so intertwined!
This book makes a somewhat sophisticated math concept accessible to elementary age kids, although it helps if the reader has experience with number patterns. Simple, striking photographs illustrate the concept beautifully, and the last page in the book expands on related concepts like the Golden Ratio and Lucas numbers for those readers who want to know more. Fabulous and simple non-fiction about a concept unusual in children’s books.
