How do you turn boring arithmetic into a fun game? You don't, because I already did it for you by mashing together Tic-Tac-Toe and Subtraction. This workbook has 26 second-grade pages, 26 third-grade pages, and 26 fourth-grade pages. And every page has nine subtraction problems to solve (and a matching tic-tac-toe challenge that students play when they solve it correctly). Every child will want to work on these pages.
If your students like games and challenges, then this workbook is what you need. If you want your child to master their Common Core Standards, then this workbook is for you. And, if you are interested in more tic-tac-toe activities, then take a look at the other workbooks in this series:
