A scavenger hunt is a fun way to get your students up and out of their seats to practice skills. Post each question on the walls around the room. The students will start at any card. They will find the answer to the problem on the card and then find their answers on another card in the room. The problem on that card is the new problem they work.
This scavenger hunt covers adding and subtracting mixed numbers involving regrouping not renaming of fractions.
