A math worksheet generator with answer keys

How do I make a printable math worksheet with an answer key?

Choose the operation first, then the range of numbers. The smallest and largest number boxes control every number in the problems, so 0 and 10 gives facts within ten, 10 and 99 gives two digit work, and 100 and 999 gives three digit work. Pick how many problems you want, from 10 to 40, and whether they sit stacked in columns or written across in a line.

The answer key is a second page with every problem and its answer in bold, numbered to match the worksheet. Print both pages, keep the key, and hand out the worksheet. Each worksheet has lines for a name, the date and a score out of the number of problems.

Why does the same link print the same worksheet?

The problems are random, but they are random in a repeatable way. They are worked out from your settings and the sheet number, so the same settings and the same sheet number always give exactly the same problems. That means you can copy the link, send it to a colleague or a parent, and they will print the identical sheet with the identical answer key.

When you want new problems, change the sheet number to 2, 3, 4 and so on. A useful habit for teachers is to note the sheet number in a planner, so a missing sheet or a lost answer key can be reprinted exactly, even weeks later.

What number ranges suit each year group?

Every curriculum sets its own expectations, so check what your school or state uses. As a rough guide, many children start with addition and subtraction within 10, then within 20, then move to two digit numbers. Multiplication usually starts with the 2, 5 and 10 times tables before the rest up to 12.

Start a little easier than you think. A sheet a child can finish with most answers right builds confidence and fluency, and you can raise the range on the next sheet.

• Number bonds and early addition: smallest 0, largest 10.
• Facts within 20: smallest 0, largest 20.
• Two digit practice: smallest 10, largest 99.
• Times tables to 12: multiplication, smallest 1, largest 12.
• Division facts: division, smallest 1, largest 12, which gives whole number answers up to 12.

How are subtraction and division problems made?

Subtraction problems never go below zero: the bigger number always comes first, so every answer is a whole number of zero or more. Division problems are built backwards from the answer. The generator picks a divisor and an answer from your range, multiplies them to get the number being divided, and so every division has a whole number answer with no remainder.

Mixed sheets pick an operation at random for each problem and follow the same rules, which makes them good for a quick review at the end of a unit. In the vertical layout, division is shown in the long division style, ready for children to write the answer on top.

How can teachers and parents get the most from practice sheets?

Short, regular practice tends to beat long sessions. A sheet of 10 to 20 problems a few times a week keeps facts fresh without turning maths into a chore. Time the sheet now and then, and let children compare with their own last score rather than with each other.

Use the answer key for marking, or let children check their own work once they finish. Looking back at which facts went wrong is often more useful than the score.

1. Print sheet 1 and let the child work through it without help.
2. Mark it with the answer key and circle the facts that were wrong.
3. Practise those facts out loud or with objects.
4. Print sheet 2 with the same settings for fresh problems at the same level.
5. Raise the largest number once most answers are right and quick.

How do I print the worksheet and answer key?

Choose A4 or US Letter under Paper and press Print or save as PDF. The worksheet is page one and the answer key is page two, so to print only the worksheet, set the page range to 1 in your print dialog, or turn the answer key off. Ink saver mode keeps the sheet readable on a black and white printer, and the sheet number prints in the footer so you always know which answer key belongs to which worksheet.
