Subtract 3 Digit Numbers With Regrouping Practice Activities
Printable Grade 4 subtraction worksheets for subtracting 3-digit numbers with regrouping across ones, tens, and hundreds.
Practice that builds confidence
What students practise
These Grade 4 math worksheets give students focused practice subtracting 3-digit numbers with regrouping. Children work with minuends and subtrahends in the hundreds, using place value to borrow from tens or hundreds when a digit is not large enough to subtract.
The printable activities include vertical subtraction problems, mixed regrouping patterns, and space for showing the regrouped numbers clearly. They are useful for independent practice, homework, review, or small-group support within the subtraction unit.
Students strengthen the standard subtraction algorithm for 3-digit numbers, such as 642 - 278 or 503 - 146. The work centers on place value: ones, tens, and hundreds. When the ones digit cannot be subtracted, students regroup 1 ten as 10 ones. When the tens digit cannot be subtracted, they regroup 1 hundred as 10 tens. Some problems require one regrouping step, while others require regrouping in more than one place.
How the skill progresses
A good progression begins with clearly aligned vertical problems where every digit has its own column. Students first identify the minuend, the subtrahend, and the difference. Then they subtract from right to left, checking whether regrouping is needed before calculating each column. Problems with zeros, such as 704 - 258, are especially important because students must understand that a hundred may need to be traded through the tens place before the ones can be regrouped.
Parent practice routine
At home, choose a short set of problems and ask your child to read each number aloud before solving. Have them circle the column that needs regrouping, rewrite the changed digits above the problem, and explain the trade in words: “I changed 1 ten into 10 ones.” After each answer, encourage an estimate, such as 642 - 278 is close to 640 - 280, so the answer should be about 360. This helps children catch unreasonable differences without turning practice into a guessing task.
Classroom uses for teachers
Teachers can use these worksheets for warm-ups, math centers, guided practice after modeling, or targeted review before multi-step word problems. The clean vertical format supports students who are still building accuracy with digit alignment. For intervention groups, have students use base-ten blocks or quick place-value drawings beside selected problems, then move back to the written algorithm.
Common errors to watch for
Watch for students subtracting the smaller digit from the larger digit within a column, regardless of order. Another common mistake is regrouping but not reducing the digit borrowed from, such as changing 32 ones but leaving the tens digit unchanged. Zeros can also cause confusion when students try to borrow from a zero without moving to the hundreds first.

Why iBloom worksheets help
This collection keeps the focus on one Grade 4 subtraction skill, so practice feels purposeful rather than scattered. A child-friendly strategy is: line up, look right, regroup if needed, subtract, then check with an estimate. Repeating that routine across carefully chosen 3-digit problems builds both accuracy and confidence.
Helpful answers
Frequently asked questions
What does regrouping mean in 3-digit subtraction?
Regrouping means trading one place-value unit for smaller units, such as changing 1 ten into 10 ones or 1 hundred into 10 tens, so a subtraction column can be completed.
Are these worksheets suitable for Grade 4 students who still make borrowing mistakes?
Yes. The worksheets focus only on subtracting 3-digit numbers with regrouping, which gives students repeated practice with the exact steps that often cause errors.
Do the problems include regrouping across zeros?
The collection is designed for 3-digit subtraction with regrouping, including patterns where students may need to think carefully about tens and hundreds. Problems involving zeros are useful for building deeper place-value understanding.
How can I help my child check a 3-digit subtraction answer?
Ask your child to estimate first or after solving. For example, 642 - 278 is close to 640 - 280, so the answer should be near 360. They can also add the difference back to the subtrahend to see if it equals the starting number.
Should students use base-ten blocks with these worksheets?
Base-ten blocks or place-value drawings can help when a student does not understand why regrouping works. Once the trade makes sense, students can move back to the written subtraction algorithm.
