Starred Review
This book is a very simple picture book that demonstrates exponents with snowflakes — on each page, the number of snowflakes doubles.
The main text is simple rhymes. The first few spreads go like this:
Two flakes play.
Four flakes sashay.
Eight flakes twirl.
Sixteen flakes swirl.
On the opposite page from the main text, we’ve got the number of snowflakes expressed with numerals and equations, like this:
27 = 2 to the seventh power
2 x 2 x 2 x 2 x 2 x 2 x 2 = 128
The scenes behind the snowflakes look like suburban backyards, with at least one animal visitor on each page.
The most wonderful thing about this book is that the illustrator worked to get exactly the right number of snowflakes on each page. Here’s what she says in a note at the back:
Creating the art for The Power of Snow presented one tricky problem: how to show the correct number of snowflakes on each page. For this book, it was important to get the math right! Of course, the first few pages were easy. But as the quantity of flakes increased, it became much harder to count them all. So I worked out a plan. The images were created using different layers, kind of like clear sheets with different parts of the art on each one. I created a certain number of flakes on one layer. Then I duplicated this layer, flipping, scaling, and rotating it to give a natural look. Duplicating the layer allowed me to multiply the exact number of flakes as I worked. I could then add the more detailed snowflakes, counting these out individually to get to the total number. As with real snow, once the flakes became tiny and overlaid, some appear to blend together — but they are all there!
The effect is that you won’t be able to count all 16,384 flakes on the page for 214, but you can definitely get the idea.
Okay, my first reaction to this book is that it’s for a young reader — primary grades or even preschoolers who haven’t learned to multiply yet, so why are they illustrating exponents to such young readers? I do wish the word “doubled” was used, instead of relying on the multiplication notation.
But then I think about the things I showed my own kids when they were young, and I’m sure that kids exposed to this book will have an easier time understanding exponents later. In fact, hmmm, this might be a wonderful gift for my four-year-old nephew who has two big sisters. When they read it to him, they will pick up the ideas… and he will think exponents are the most natural thing in the world when it finally comes time to learn about them in school.
Yeah, I think I’m won over. Doubling before your eyes!
