Add or Subtract with Regrouping Two Digit

Before handing out the worksheet, briefly introduce the concept with a short oral warm-up or a visual model on the board. Let students work through it independently after a quick group example, checking in with a partner if they get stuck, encouraging them to talk through their thinking: "What strategy are you using? How do you know that is right?" After completing the worksheet, review any missed problems together and discuss the reasoning rather than just the answer. For extra support, let students use manipulatives or draw pictures alongside the written problems. These mixed addition and subtraction (2 digits) worksheets work well as daily practice, homework, or a focused review activity.

Circle the sign, then add or subtract 2-digit numbers in columns, all with regrouping. Plus (+) means add and minus (−) means subtract. Regroup when a column makes 10 or more, or when a top digit is too small. The directions on the page read: Circle the sign in each problem. Then, add or subtract, and write any regrouped digits above the columns. The answer key shows every answer.

Yes, both. We made it for 2nd Grade subtraction, and the page works the same whether it lands on a kitchen table or a center rotation. At home, most families go through it together and talk the answers out loud, and that talking is where most of the learning happens with mixed addition and subtraction (2 digits). In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.

Reading the operation sign before each problem and resisting the urge to apply the same procedure to every equation - a metacognitive habit that reduces careless errors significantly.

Yes - mixing all four combinations (adding with/without carrying, subtracting with/without borrowing) most accurately represents the range of problems students encounter on assessments.

Students who check their answers by applying the inverse operation (e.g., verifying a subtraction result by adding back) develop a verification habit that improves accuracy across all computation.

Second graders should fluently subtract within 20 (CCSS 2.OA.B.2) and subtract within 100 using strategies based on place value (2.NBT.B.5). They also begin subtracting within 1,000 with models and drawings (2.NBT.B.7).

Start with base-ten blocks: show that when you cannot subtract the ones, you trade one ten for 10 ones. Practice this physically before moving to paper. Worksheets that show the regrouping step-by-step help students internalize the process before working independently.
