Kindergarten Addition Worksheets — Sums to 10, Free PDF
Kindergarten addition is counting made official: putting two small groups together and counting on to find the total. Two skills share this topic — Add Within 10 and Addition Stories — and each one has its own page and its own three levels. Add Within 10 keeps everything small, from two numbers up to four, so early counters always land on totals they can show on their fingers. Addition Stories asks the same sums in words. For the sheets where the blank sits inside the sum — "4 + ___ = 9" — go to the kindergarten missing numbers worksheets, whose Missing Addend page keeps every one of those within ten. Change any setting below and the worksheet updates instantly — and the page link reproduces that exact worksheet whenever you come back to it.

Each one generates a different kind of question, with its own three levels and answer key.

What addition looks like in kindergarten
Most curricula expect kindergartners to add within 10 by year-end, usually by counting objects, fingers, or drawings rather than recalling facts. The skill to build first is counting on: starting from the bigger number and counting up, instead of recounting everything from one.
Keep sheets tiny — 6 to 10 problems — and stay on Add Within 10 all year, nudging the level from Two numbers to Three numbers as counting gets surer. If a problem like 4 + 3 gets solved by counting "one, two, three, four... five, six, seven," that is exactly right for this age; speed is not the goal yet.
Making practice work for a 5-year-old
Print the sheet and put real objects next to it — buttons, blocks, cereal — so every written problem can be built and counted. Type your child's name into the name field and it prints at the top of the sheet, which makes it feel like their own work; the name never leaves your device.
Watch for two common slips: recounting the first group from one every time, and writing reversed digits. Neither is a worry at this age. When most sums to 10 come without finger-counting, the next step is moving the blank into the middle of the sum — working out "4 + ___ = 10" is the number-bond thinking that subtraction is built on next year. That sheet lives on the kindergarten missing numbers worksheets rather than here: its Missing Addend page keeps every total at 10 or under across all three of its levels.
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.
