RJ and Zoey are at camp and need to get back to the mess hall for lunch, but they don't know how far they have to walk. Help them figure out the distance while teaching young mathematicians how to add and subtract fractions with this step-by-step presentation.

A great resource to implement during whole-group instruction or as an in-class or homework assignment following a lesson on addition and subtraction of fractions.
