These are 60 two and three digit addition and subtraction worksheets for students who are practicing these problems both with and without regrouping. There are 20 problems on each worksheet. They are both mixed (addition and subtraction) and separated (just addition, just subtraction and with regrouping and without regrouping). These are great for warm ups, reviews, homework, classwork, independent work, etc. Each worksheet has a nice theme. Enjoy!
