Three Digit Subtraction Regrouping Twice

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 subtract a 3-digit number from a 3-digit number with borrowing worksheets work well as daily practice, homework, or a focused review activity.

Subtract 3-digit numbers in columns, regrouping in both columns. To regroup in subtraction, trade 1 hundred for 10 tens or 1 ten for 10 ones. Write the new digits above. The directions on the page read: Subtract the ones, then the tens, then the hundreds. When the top digit is smaller, regroup and write the new digits above. 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 subtract a 3-digit number from a 3-digit number with borrowing. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.

Students may need to borrow only in the ones column, only in the tens column, or in both - and each column's borrowing affects the digit in the column to its immediate left.

First check the ones column; if borrowing is needed, reduce the tens digit by 1. Then check the tens column; if its (now possibly reduced) digit requires borrowing, reduce the hundreds digit by 1.

CCSS 3.NBT.A.2 requires fluent addition and subtraction within 1,000; 2nd grade practice with 3-digit borrowing gives students a significant head start on this standard.

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.
