How to make a math worksheet with an answer key

Choose a grade of primary school and a difficulty and it picks sensible number ranges, or set the operations, ranges, carrying and remainders yourself. Children can type their answers and check them on screen, and teachers can print the same problems with an answer key.
- Choose the grade (1º to 6º) and the difficulty: easy, medium or hard.
- Pick how many problems you want, from 10 to 50, and the layout: in a row or stacked in columns.
- Open Custom settings to choose the operations, the smallest and largest numbers, carrying and borrowing, and division with remainders.
- Type the answers and press Check answers: right answers turn green and wrong ones show the correct result.
- Add a title, choose US Letter or A4 and download the PDF: worksheet pages first, then the answer key.

Yes. The PDF always adds answer key pages after the worksheet, and on screen you can check the answers at any time.
How are divisions with remainders written?
As quotient r remainder, for example 17 ÷ 5 = 3 r 2. Turn remainders off to get only exact divisions.

Can I print the same worksheet again later?
Yes. Copy the link to the worksheet: it stores the worksheet number, grade, difficulty and number of problems, so it rebuilds exactly the same problems.
