2-Digit Subtraction with Regrouping Grade 2 Free PDF Worksheet

Learn 2-Digit Subtraction with Regrouping – Grade 2 Practice Worksheet

This printable 2-digit subtraction with regrouping worksheet is designed for Grade 2 students who are learning how to subtract larger numbers step by step. Regrouping, also called borrowing, is one of the most important skills children learn in early math because it introduces place value understanding and more advanced subtraction methods.

Many students feel confident subtracting numbers like 54 − 22, but they often struggle when borrowing is required. Problems such as 42 − 18 or 31 − 16 need regrouping because the number in the ones column is smaller than the number below it. This worksheet gives children repeated practice so they can learn the process naturally and improve their accuracy.

What Is 2-Digit Subtraction with Regrouping?

2-digit subtraction with regrouping happens when the top digit in the ones place is smaller than the bottom digit. In this case, students borrow one ten from the tens column and convert it into ten ones.

For example:

42 − 18

• The ones column is 2 − 8
• 2 is smaller than 8
• Borrow 1 ten from 4 tens
• Now the ones column becomes 12 − 8
• 12 − 8 = 4
• 3 − 1 = 2
• Answer = 24

This borrowing process helps students understand place value and prepares them for larger subtraction problems later.

Step-by-Step Method for Regrouping

Students can use this simple process every time:

• Step 1: Write numbers vertically by place value.
• Step 2: Start subtracting from the ones column.
• Step 3: If the top digit is smaller, borrow 1 from the tens column.
• Step 4: Add 10 to the ones place.
• Step 5: Complete the subtraction.
• Step 6: Finish the tens column.

Practicing these steps repeatedly helps children solve subtraction problems more quickly and with fewer mistakes.

Worked Examples

Example 1: 31 − 14

• Ones: 1 cannot subtract 4
• Borrow 1 ten → 11 − 4 = 7
• Tens: 2 − 1 = 1
• Answer: 17

Example 2: 54 − 27

• 4 cannot subtract 7
• Borrow from tens
• 14 − 7 = 7
• 4 − 2 = 2
• Answer: 27

Example 3: 70 − 35

• 0 cannot subtract 5
• Borrow from 7 tens
• 10 − 5 = 5
• 6 − 3 = 3
• Answer: 35

Easy Practice Tips for Students

Learning regrouping becomes easier when students practice small steps instead of rushing through problems.

• Always begin from the ones column.
• Circle the digit that needs borrowing.
• Cross out the tens digit after borrowing.
• Use grid paper to keep numbers aligned.
• Practice 5–10 problems daily instead of many at once.
• Read answers aloud to reinforce learning.

Short daily practice sessions are often more effective than long study periods.

Common Mistakes Students Make

1. Forgetting to Borrow

Students sometimes subtract directly even when borrowing is required.

Example:

31 − 15

Incorrect: 1 − 5

Correct method: borrow first.

2. Not Reducing the Tens Digit

After borrowing, the tens digit decreases by one. Many students forget this step.

3. Mixing Tens and Ones

Keeping numbers aligned vertically helps avoid place value mistakes.

4. Rushing Through Problems

Slow and careful subtraction often produces better results than speed.

Why Is Regrouping Important?

Regrouping builds strong number sense and prepares students for larger operations such as:

• 3-digit subtraction
• Money calculations
• Mental math
• Word problems
• Advanced arithmetic

Students who understand regrouping usually become more confident in future math lessons.
