Reach for this book when your child starts asking questions that reach beyond the clouds, such as how many stars are in the sky or how long ago the dinosaurs lived. It is the perfect tool for a child who has mastered basic counting and is now ready to grapple with the awe-inspiring scale of the universe. Through clever illustrations and relatable comparisons, Robert E. Wells transforms abstract mathematical concepts into a tangible sense of wonder. While the primary focus is STEM education, the book taps into a deep sense of curiosity and the pride a child feels when they can name something as massive as a googol. It frames math not as a series of drills, but as a language for understanding the cosmos. This is an ideal choice for elementary-aged children who are beginning to realize just how big the world really is and want a way to measure it.
The book is entirely secular and scientific. It mentions the age of stars and the era of dinosaurs, which may be a point of consideration for families who prefer a strictly young-earth creationist perspective, but the treatment is standard non-fiction educational fare.
A second or third grader who is the resident 'expert' on space or dinosaurs in their classroom. This child loves facts, figures, and being able to explain complex things to adults.
Read the final page first so you can share the fun anecdote about nine-year-old Milton Sirotta naming the googol. No complex prep is needed, though being ready to talk about scientific notation might help with older kids. The child asks, "What is the biggest number in the world?" or expresses frustration that they can't imagine how far away the sun is.

Unlike many math books that stay in the realm of arithmetic, Wells connects 'big math' to 'big science,' showing kids exactly why these numbers matter in the real world.
The book uses a ladder-like progression to introduce powers of ten. Starting with simple numbers, it quickly scales up through millions, billions, and trillions, using visual metaphors (like stacks of blocks or groups of animals) to show volume and distance. It eventually reaches a googol (1 followed by 100 zeros) and explains its origin story involving a mathematician's nephew.
