Frequently Asked Questions

What grade learns addition within 20?

First grade. By the end of the year children are expected to add within 20 and know sums within 10 from memory.

Do the math worksheets come with answer keys?

Yes. Every worksheet prints with a matching answer page, with the answers in green.

Will subtraction problems have negative answers?

No. The bigger number always goes on top, so every answer is zero or more.

Do division problems have remainders?

No. Each problem is built from a multiplication fact, so every answer is a whole number.

Can I make a worksheet for just one times table?

Yes. Choose multiplication or division, switch on "Practise one times table" and pick the table.
