Math worksheets for 2nd graders. Two-digit addition and subtraction with and without regrouping, plus mixed practice. Download, print, and build fluency.
Second grade math introduces two-digit addition and subtraction, including the critical skill of regrouping (carrying and borrowing). Our worksheets provide structured practice at each level — start with problems that don't require regrouping, then build to problems that do. Mixed operation worksheets help students stay sharp on both skills.
These worksheets align with Common Core standards for 2nd grade: fluency with addition and subtraction within 100 (2.NBT.5) and adding within 1000 using place value strategies (2.NBT.7). Every worksheet includes an answer key. Print as many copies as you need — each generates fresh problems.
