4-Digit Subtraction Worksheets

Set Borrowing to None on the first day so a child can practice lining up the columns without any trades. Move to Every problem once the method has been taught, and keep Mixed for Friday quizzes. Twelve problems take most children about ten minutes; thirty is closer to a full homework slot. Ask the student to work one column at a time and cross out the lending digit neatly. Check with the answer key, then circle only the columns that went wrong instead of the whole problem. The 5 versions switch gives each table its own sheet.

Four-digit subtraction is place value under pressure. The student trades a thousand for ten hundreds, or a hundred for ten tens, and then has to carry that change across a zero without losing track. Most errors come from subtracting the smaller digit from the larger one regardless of position, or from forgetting to reduce the digit that lent. Three-digit subtraction comes first, and multi-step word problems usually follow. Missing number mode hides one number in each problem so the child works it out from the rest, which checks the same facts from the other direction.

For a child still shaky on trading, use twelve problems with None, then the same count with Every problem a day later. Stronger students can take thirty on Mixed as a timed check. Stacked gives the most room for crossing out digits, In a row suits estimating before solving, and Compact fits a review on one sheet. Save Missing number mode for a challenge once the plain version is steady.

Can an answer come out negative?

No. The bottom number is never larger than the top, so every answer stays positive. Both numbers are full four-digit numbers, so the sheet stays on borrowing across the thousands place. Use the three-digit page for smaller numbers.

What is the difference between Every problem and Mixed?

Every problem needs a trade in at least one column on each line. Mixed gives a spread, with some lines that borrow and some that do not, which is how a test page usually looks. None removes borrowing completely.

How many problems should a fourth grader do at once?

Twelve to twenty is plenty while the method is new. Twelve leaves wide work space and takes about ten minutes. Thirty makes a fluency check for children who already borrow across zeros without stopping to think.
