Course Overview

In this course, we will examine David Schwartz's book: If You Hopped Like a Frog with a mathematical eye toward understanding the comparisons he makes. Once we understand how to make such a statement, we will get creative and come up with our own ideas of proportional reasoning. Students will gain confidence in how to write  proportions and solve for an unknown. 

The opening line of the book is: “If you hopped like a frog, you could jump from home plate to first base in one mighty leap!” Are you curious how the author figured that out? Join us to explore proportional reasoning! 

Student Outcomes:

  • Practice research skills, seeking  interesting “feats of strength” in the animal kingdom to apply proportional reasoning to 
  • Apply knowledge of proportional reasoning and solving for an unknown
  • Work together to write and illustrate a new book of creative, proportional statements
