About this worksheet maker

Everything is generated in your browser — no account, no watermark, no limit. Each worksheet has a number from 1 to 9999: the same settings and number always rebuild the same problems, so “Copy link” lets you share an exact sheet with a class or reprint it next week. Problems on one sheet don't repeat unless the level is too small to fill it. Subtraction never goes below zero, and division with “No remainder” always divides exactly. Turn on “Solve on screen” to type answers and check them instantly.

Suggested settings by school year

Curricula differ from country to country, but most follow the same order: addition and subtraction within 20, then two- and three-digit numbers with regrouping, then the times tables, and finally multi-digit multiplication and long division. Use the list below as a starting point and move up a level once a full sheet is mostly correct without hesitation.

A good order for carrying and borrowing

Regrouping is the step where most mistakes happen, so it pays to separate it. Begin a new level with “No regrouping”: the student only has to line up the digits and work column by column. When that is easy, switch to “Always”, where every problem needs at least one carry or borrow, so the new step is practised on every line instead of once in a while. Finish with “Mixed”, which is closest to real tests: the student has to notice on their own when a column needs regrouping.

Subtraction answers are never negative on these sheets, and a 1-digit minus 1-digit problem can never need borrowing — to practise borrowing for the first time, choose “2-digit & 1-digit” (for example 32 − 7).

Why the vertical layout helps

In the vertical (column) layout, ones sit under ones and tens under tens, which is exactly what the standard written method needs. It leaves room above each column to write the carried 1 and to cross out a borrowed digit, and the long-division format shows the divisor, the dividend and the space for each step. Horizontal problems are better for quick fluency and mental strategies, so many teachers alternate: vertical while learning the method, horizontal once it is automatic. Horizontal sheets fit up to 100 problems on a page; vertical sheets up to 30 (20 for long division and 2-digit × 2-digit, which need working space).

Checking and repeating

Print the worksheet and the answer key together with “Print both”, or check on screen with “Solve on screen” — wrong answers are marked and the correct answer appears next to them. The most useful thing to look at is not the score but which problems were wrong: if every mistake is in a column that needed carrying, go back to “Always” for that level for a few days.

Short, frequent practice works better than one long session. A good routine is the same sheet number twice in a week: once to learn, once a few days later to see what stuck. Because the number rebuilds the exact same problems, the second try is a fair comparison.

Frequently asked questions

Are these math worksheets really free to print?
Yes. Every worksheet is generated in your browser with no account, no watermark and no limit on how many you make or print. Teachers and parents can use them in class or at home.
How do I print the answer key?
Press “Print answer key” for the answers only, or “Print both (2 pages)” for the worksheet followed by its answer key. Each one fits exactly on one A4 page. To keep a file, choose “Save as PDF” in the print dialog.
Can I get the same worksheet again or share it?
Yes. The same settings and sheet number always produce the same problems. Note the number printed on the sheet, or press “Copy link”: the link opens that exact worksheet on any device.
What do “None”, “Always” and “Mixed” regrouping mean?
“None” means no column ever adds up to 10 or more (or, in subtraction, no top digit is smaller than the one below it). “Always” means every problem has at least one such column. “Mixed” makes roughly half of each.
How are division remainders written?
Choose “With remainder” or “Mixed” and each division gets a second box: in horizontal problems the answer is written as quotient … remainder (17 ÷ 5 = 3 … 2); in long division there is an “R” box under the problem. With “Mixed”, a remainder of 0 can be left empty when solving on screen.
Why can't I choose more than 30 problems in the vertical layout?
Column problems need space to write carries and partial results, and every sheet is sized to print on exactly one A4 page. Vertical sheets hold up to 30 problems, and 20 for long division and 2-digit × 2-digit. For more practice on one page, use the horizontal layout (up to 100).
