This game is 3-digit addition with and without regrouping. I like to have my students practice the skills taught with games and not worksheets. They get enough worksheet practice in their math workbooks. This game is one I used to have my 5th graders play with various skills. I like that it is easy to assemble and uses a Pringles can which is relatively easy to get and recycle with contact paper and a label. This game can be played whole group with teams or as a partner practice game.
