How to make a addition worksheet

Choose the number of digits: 1, 2 or 3. This sets how big the numbers are and how hard the sheet feels.
Choose vertical problems (stacked, the way children learn to add with a pencil) or horizontal problems (written on one line, good for mental math).
Pick how many problems you want on the page: 12, 16, 20, 24 or 30. Turn on problem numbers if you want to say "look at number 7" while you check the work, and keep the numbers bold for easy reading.
Press Create. The preview shows the page exactly as it will print. Press Download PDF to save the sheet, or Print to send it straight to your printer. Press Create again whenever you want a fresh set: the numbers change, the layout stays the same.
Press Show answers to see the same sheet with every answer in red. Download or print it as your answer key.

Which settings for which grade

Kindergarten and early 1st grade: one-digit problems, 12 or 16 per page, vertical. Children add numbers up to 9 + 9, which is exactly the set of facts they need to know by heart. Counters, fingers or a number line on the table are welcome at this stage.

1st and 2nd grade: two-digit problems. Some will need regrouping (carrying) and some will not, so the sheet practises both. If regrouping is new, start with 12 problems and work the first two together, saying each step out loud: add the ones, write the ones digit, carry the ten.

3rd grade: three-digit problems, 20 or more per page. These are good for practising regrouping across two places, for example 487 + 356.

Tips to make addition practice stick

Before writing anything, ask your child to estimate. Is 48 + 37 nearer 70 or 90? Estimating catches many mistakes before they happen.
Use the horizontal layout for mental math. Problems like 25 + 30 on one line push children to think in tens instead of reaching for the pencil.
Time it now and then, not every day. Beating last week's time is motivating, but a stopwatch on every sheet can make children anxious.
Let older children mark their own sheet with the answer key, then redo only the problems they got wrong.

Using the sheets at home and in class

At home, one sheet after school is enough: ten minutes, then something fun. Keep the finished sheets in a folder, and every few weeks print one with the same settings to show your child how much faster and more accurate they have become. In class, the generator makes differentiation simple: print one-digit sheets for children who are still building their facts and two-digit sheets for those ready to regroup, so everyone works on the same skill at the right level.

What is on the printed page

Each sheet has a clear title, a line for the child's name and the date, and a neat grid of addition problems with plenty of room to write. The font is large and simple, the page is uncluttered, and it prints well in black and white. Because the numbers are random, two sheets with the same settings are never the same, which makes the generator handy for daily practice, homework and quick checks before a test.

Frequently asked questions

Does the addition generator include regrouping?

With two or three digits, some problems need regrouping and some do not, chosen at random. That mix is useful practice, because children must decide when to carry.
