Beanstalk: The Measure of a Giant (A Math Adventure)

Book Reviewby Ann McCallum
Available at Amazon.com

Summary: This book is a twist on Jack and the Beanstalk.  Jack climbs the beanstalk to meet a young giant, Ray.  Ray and Jack become friends, and play all sorts of games together.  They use ratios to make the games work for boy and giant.  They create a hoop for Jack proportionate to Ray’s hoop for a toss game.  Jack constructs a checkers game Ray can play.  They describe all this to Jack’s mom and explain what they were doing: “Ray shows” – ratios.

Activities: I would use this as a Read-Aloud for grades 4-6.  For sixth grade, where ratios are part of the curriculum, I would use it to teach the subject.  I might use it for a math lesson for mathematically advanced fifth graders.
