I used this mad lib to review adding and subtracting fractions with unlike denominators. This is a quick review with focus on unlike denominators (the difficulty level of the problems is easy to medium depending on your grade level and student abilities).
I printed off a class set of problems/answers and each student was given their own copy of the mad lib. I printed two mad libs on one page to save paper!
Included are the mad libs, the problems/answers (one page), and the answer key for the teacher.
