I teach 6th grade so I created this activty to give my students some extra practice on just regrouping before we started doing subtraction.
There are two sets that can be used seperately or together. The first set is regrouping/borrowing from a whole. The second set is regrouping mixed numbers into a mixed number with an improper fraction.
I like to copy these on colored paper and then have my students cut/paste/match them in their notebooks. These would be good for a center though if you laminate them.
