3 Digit Subtraction with Regrouping Worksheets

3 digit subtraction with regrouping worksheets help students in Grades 2–3 practice subtracting hundreds, tens, and ones when borrowing is required. Brighterly’s printable activities include standard three-digit subtraction, regrouping across multiple place values, and more challenging problems that involve borrowing across zero.

These worksheets build on place value and basic subtraction skills. Students who need to review the broader regrouping method first can use Brighterly’s subtraction with borrowing worksheets.

3 Digit Subtraction with Regrouping Worksheet: Examples

Brighterly’s worksheets help students line up hundreds, tens, and ones correctly before regrouping where needed. Problems range from straightforward borrowing to subtraction across zero.

For example:

503 − 278 = 225

This problem is more challenging because the tens digit in 503 is zero. Students need to regroup from the hundreds place before they can borrow into the ones column.

For broader Grade 3 practice with subtraction facts, larger numbers, word problems, and regrouping, students can also use 3rd grade subtraction worksheets.

If multi-digit regrouping is still challenging, a 3rd grade math tutor can provide targeted practice with place value, subtraction, and other Grade 3 arithmetic skills.

How to Subtract 3 Digit Numbers with Regrouping

Students should write the numbers vertically and line up the hundreds, tens, and ones before subtracting from right to left.

For example:

352 − 178

1. Start with the ones: 2 − 8 cannot be done using whole numbers, so regroup 1 ten. The 5 tens become 4 tens, and the 2 ones become 12 ones.
2. Subtract the ones: 12 − 8 = 4.
3. Now subtract the tens: 4 − 7 is not possible without regrouping, so borrow 1 hundred. The 3 hundreds become 2 hundreds, and the 4 tens become 14 tens.
4. Subtract the tens: 14 − 7 = 7.
5. Subtract the hundreds: 2 − 1 = 1.

Therefore:

352 − 178 = 174

Brighterly’s subtraction with regrouping guide explains the same borrowing process step by step.

How to Subtract Across Zero

Subtracting across zero requires an extra regrouping step because there is nothing available to borrow directly from the tens place.

Consider:

503 − 278

Start with the ones column. Since 3 is smaller than 8, students need to borrow. However, the tens digit is 0, so they first regroup 1 hundred:

5 hundreds → 4 hundreds

The borrowed hundred becomes 10 tens. Then regroup 1 of those tens into 10 ones:

10 tens → 9 tens and 13 ones

Now subtract each column:

• 13 − 8 = 5
• 9 − 7 = 2
• 4 − 2 = 2

So:

503 − 278 = 225

This type of problem reinforces the idea that regrouping changes how a number is represented without changing its total value.

Why Place Value Matters in 3 Digit Subtraction

Regrouping works because the base-ten number system lets students exchange 1 hundred for 10 tens or 1 ten for 10 ones.

For example, 503 can be represented as:

5 hundreds + 0 tens + 3 ones

or, after regrouping:

4 hundreds + 9 tens + 13 ones

Both representations have the same total value. Understanding this relationship makes borrowing more meaningful instead of turning it into a memorized rule.

Students who need extra support with hundreds, tens, and ones can review Brighterly’s place value guide.

Skills Students Practice with 3 Digit Subtraction

• Align hundreds, tens, and ones. Students practice writing numbers in the correct place-value columns before beginning the calculation. Proper alignment helps prevent common subtraction errors.
• Regroup from the tens place. When the ones digit in the minuend is smaller than the ones digit being subtracted, students exchange 1 ten for 10 ones.
• Regroup from the hundreds place. Some problems require students to borrow from the hundreds column before they can complete subtraction in the tens column.
• Subtract across zeros. Problems such as 503 − 278 require students to regroup through a zero, making them useful practice for understanding how borrowing works across multiple place values.
• Check subtraction with addition. Students can verify an answer by adding the difference and the subtrahend. For example: 225 + 278 = 503. This confirms that 503 − 278 = 225.
• Build multi-digit arithmetic fluency. Repeated three-digit subtraction practice helps students become more accurate with borrowing while preparing them for calculations involving even larger numbers.

3 Digit Subtraction vs General Subtraction with Borrowing

This worksheet collection focuses specifically on subtracting three-digit numbers, including regrouping through the hundreds, tens, and ones places and borrowing across zero.

Students who want mixed practice with both operations can use addition and subtraction with regrouping worksheets.

What Comes After 3 Digit Subtraction with Regrouping?

Once students understand regrouping with three-digit subtraction, they can apply the same place-value reasoning to other multi-digit operations.

For example, 3 digit addition with regrouping worksheets reinforce carrying across the ones, tens, and hundreds columns.

Parents can also use Brighterly’s guide on how to teach subtraction for additional regrouping strategies and worked examples.

Frequently Asked Questions

How Do You Subtract 3 Digit Numbers with Regrouping?

Line up the hundreds, tens, and ones, then subtract from right to left. If the top digit in a column is smaller than the digit below it, regroup 1 unit from the next place-value column. Continue until each column can be subtracted.

How Do You Subtract 3 Digit Numbers Across Zeros?

When the next place-value digit is zero, regroup from a farther-left column first. For example, in 503 − 278, regroup 1 hundred as 10 tens, then regroup 1 of those tens as 10 ones. This gives 4 hundreds, 9 tens, and 13 ones before subtraction.

What Grades Practice 3 Digit Subtraction with Regrouping?

Students typically work with 3 digit subtraction with regrouping in Grades 2–3. They build on place value and basic subtraction skills before solving problems that require borrowing across tens, hundreds, and zeros.
