Subtracting Multi-Digit Regrouping Worksheet

Regrouping is the moment multi-digit subtraction stops being a routine and starts being a decision, and this Subtracting Multi-Digit Regrouping Worksheet gives fourth graders six full six-digit problems that each demand it. When a digit on top is smaller than the digit below it, the student has to trade a ten from the next column over and keep track of what that trade changed — the exact skill 4.NBT.B.4 asks for, and the exact place where careful students still lose points.

The sheet is built to be worked straight down the page. Part A holds six column problems laid out on a place-value grid, so ones sit under ones and thousands under thousands and a student can see the borrowing rather than guess at it. Every problem regroups between two and four times, including trades that cross more than one column, so no item can be finished by inspection. Part B turns the procedure into thinking: a one-step word problem about a paper mill, then a two-step problem that requires two separate subtractions before the answer is right. The second page is a complete answer key, so this subtracting multi-digit regrouping worksheet can run as independent practice, homework, a quick assessment, or a small-group reteach.

What’s Included

• 1 print-ready PDF worksheet
• 1 answer key page
• 6 six-digit column subtraction problems, every one requiring regrouping
• 2 applied word problems, including a two-step problem
• Standard-algorithm practice aligned to 4th Grade place value

There are three reasons this 4th grade subtraction worksheet helps children learn the skill. First, the problems are set on a true place-value grid, so a student who lines the digits up correctly is rewarded and a student who does not can see immediately where the columns drifted. Second, the regrouping is varied on purpose — some problems trade once in the middle of the number and others trade three or four times in a row — so children cannot fall into a single pattern. Third, the word problems ask for the same arithmetic inside a real situation, which is how the skill is actually tested.

Teachers and parents can build on the sheet in a few simple ways. Ask a student to explain one problem out loud, naming the column being traded and what it becomes, because the explanation exposes a misconception faster than a wrong answer does. Have children estimate each difference by rounding to the nearest ten thousand before they subtract, then compare the estimate with the exact answer as a built-in check. Write one of the Part A problems on a whiteboard with a deliberate borrowing error and ask the class to find it. Keep the finished page in a math folder so students can look back at a correct example when they meet larger numbers later in the year.
