If You Hopped Like a Frog

I use this book to introduce proportional reasoning. I've created activities that extend the ideas. Great book...even for older kids.

I am a high school math teacher and I use this book to help my freshmen learn about ratios and proportions. They use the proportions to calculate how much they could swallow, how far they could jump, etc. They're astonished at the results!

This book offers a look at the wonders of the natural world by comparing the capabilities of many different animals and birds in human terms. The concept, together with the large and vivid illustrations hooked me from the beginning. This book really challenges a child to think and causes an adult to marvel at God's creations. "If you hopped like a frog...you could jump from home plate to first base in one mighty leap!...If you grew as fast in your first nine months as you did in the nine months before you were born...you would have been...heavier than 2 1/2 million elephants!" Just imagine that!

This book was so enjoyable! The pictures were great!It gave you facts, and then expanded on those facts to give you information how it would affect you. As a teacher, I could use this book as an introduction and then have my students make a spin-off class book.
