Liked this book about number sense just as much as [b:Is a Blue Whale the Biggest Thing There Is?|13783339|Is a Blue Whale the Biggest Thing There Is?|Robert E. Wells|https://d.gr-assets.com/books/1348993204s/13783339.jpg|1045406]. It explains big numbers in the best way I can think of to get a feel for them. I nice touch at the end was the last page spread that explained how to come up with the representations used in the book, for instance how do we figure out "how big a stack 1,000,000 dollar bills would make", or that "100 eagles could really take you for a ride" ...

I will always remember this book for being at the center of my first independent math lesson. For fifth-grade, my topic was multiplying with powers of ten using exponents, and Can You Count to a Googol? really helped introduce all of that math content.
What I could not have anticipated while writing the lesson plan was that the students I received this morning were completely unfamiliar with powers of ten (and I later learned that they were the lowest level group), but between all the strategies I had planned and this book, they had a beginning understanding of powers of ten and exponents by the end of the hour. If the only tidbit they take away from the lesson was that the value of the exponent is equal to the number of zeros in the product, then at least they have a headstart when they reach powers in their math class.

Great way to begin conceiving how big the BIG numbers are for kids and adults.

Perfect for 5th grade powers of ten and the largeness of what numbers represent!
