Hamsters in a car, a bored cat, and a...protractor? Teaching kids math through a story, this zany tale of survival and angles teaches children about degrees. As the hamsters attempt to take their car off jumps at greater speeds, they try 30 degree angles, sixty, ninety and finally down to 180 degrees--each illustrated with a board and a protracter, making the concepts crystal clear. 31 pages, softcover with additional math activites in the back. Recommended for ages 7 & up.
