Math worksheet generator

• Operations: any mix of addition (+), subtraction (−), multiplication (×) and division (÷). With several operations selected, problems alternate and are shuffled.
• Number range: up to 10, 20, 100, 1,000 or 10,000.
• Difficulty for addition and subtraction: Easy avoids regrouping (no carrying or borrowing), Hard always requires it, and Medium mixes both.
• 10 to 60 problems per sheet.
• Missing numbers such as ___ + 5 = 12, to practice the relationship between operations.
• Division with remainders, written as 17 ÷ 5 = 3 R 2.
• Vertical (stacked) format for multi-digit addition, subtraction and multiplication, as students write them on paper (available for ranges of 100 and up when division is not selected).

Every printout starts with a header for name, class and date, and the answer key prints on a separate page.

The Common Core State Standards set these fluency goals, which most US states follow in some form:

Grade	Typical practice	Suggested settings
Kindergarten	Add and subtract within 5–10	+, −, up to 10, Easy
1st grade	Add and subtract within 20	+, −, up to 20, Medium
2nd grade	Add and subtract within 100	+, −, up to 100, Easy then Hard
3rd grade	Multiply and divide within 100; add and subtract within 1,000	×, ÷, up to 100; or +, −, up to 1,000
4th grade	Multi-digit addition and subtraction; multi-digit multiplication	Up to 10,000, vertical format

Every class is different, so adjust to what your students are working on.

Each worksheet has a sheet code, shown in the header and on the answer key. The same settings plus the same code always produce exactly the same problems. That is useful when:

• you want to reprint a sheet for a student who was absent,
• two teachers want to give the same practice to their classes,
• you need the answer key again later.

Open Reprint an earlier worksheet by its sheet code, enter the code, click Load, and make sure the other settings match. Click New problems whenever you want a fresh set.

Print with answer key opens your browser's print dialog with the worksheet on the first page and the answer key after a page break. To save a PDF instead, choose "Save as PDF" (or "Microsoft Print to PDF") as the printer. For the answer key only, print the last page.

The preview on this page shows the problems as they will print; Show answers fills in the solutions on screen, which is handy for checking work together on a projector.

Worksheets are generated in your browser; nothing about your class is stored or uploaded.

• Short and frequent beats long and rare. Ten to twenty problems a day build fluency better than sixty once a week.
• Time it gently. Track how long a sheet takes and celebrate improvement rather than speed alone.
• Use missing-number problems once basic facts are secure; they build understanding of how addition and subtraction relate.
• Vertical format helps when students learn the standard algorithm with regrouping.

For drilling multiplication facts, the multiplication table trainer adds timed practice.
