Frequently asked questions

▸Should a kindergartner be doing addition worksheets?

In small doses, yes. Most curricula introduce addition within 10 during kindergarten, and a short 6–10 problem sheet alongside hands-on counting is a comfortable amount. If worksheets cause frustration, go back to objects only for a while.

▸What sums should a 5-year-old be able to do?

Typically sums within 10 by the end of the kindergarten year, solved by counting objects or fingers. The Add Within 10 skill keeps every problem in that range, whichever of its three levels you pick.

▸Where are the kindergarten missing number sheets?

On the kindergarten missing numbers worksheets, not here. Its Missing Addend page is the one you want — "4 + ___ = 9", the first number hidden, and the total written first — and every question on all three of its levels stays at a total of 10 or less. Addition used to carry a copy of that skill at this grade, but two of its three levels put the totals between 11 and 20, which is a Grade 1 expectation rather than a kindergarten one.

▸How do I make the worksheet easier to read for a young child?

Turn on the easy-read font and choose a large text size — you get big, clear digits with plenty of white space. The preview updates instantly so you can see the layout before printing.

▸Can I print the same worksheet twice?

Yes. The link stores your exact worksheet, so opening it again reproduces identical problems — handy for a second attempt or a sibling. Press Shuffle instead when you want fresh problems at the same settings.

▸Do I need to sign up to use this?

No account, no email required, no cost. The worksheet is generated in your browser and you print straight from the PDF — including the child's name if you typed one, which stays on your device.
