Subtracting Fractions Puzzles works on practicing the skills of subtracting fractions with unlike denominators.
This is a free 2 page sample-- the paid product has 72 puzzles to choose from. Copy on cardstock, laminate for durability year to year and cut them up. I would put several puzzles in a resealable bag so that students have to problem solve in order to solve the puzzle.
There is a mini assessment sheet on a 1/2 sheet of paper. (2 per page) After students put puzzles together you can have them fill out the sheet to show that they understand the process of finding common denominators and subtracting fractions.
