What is on this worksheet
Every visit to this page builds a fresh worksheet of 20 addition problems with answers no higher than 10, so the sheet never repeats and a child cannot memorize the page instead of the math. Sums within 10 are the foundation everything later is built on. A child who knows these without counting can move on to larger numbers, carrying and mental math, while a child still counting on fingers for 4 plus 3 will find each of those steps harder than it needs to be.

Three ways to practice
Learn the pairs that make ten
There are only five to know: 1 and 9, 2 and 8, 3 and 7, 4 and 6, and 5 with itself. These five pairs do more work than any other set of facts in early math, because they are what later strategies lean on. Pick them out of the worksheet whenever they appear and say them as a pair.
Count on from the bigger number
For 2 plus 7, start at 7 and count up two rather than starting at 2 and counting up seven. It reaches the same answer with far less counting and fewer mistakes. Children often do not think to reorder the problem, and it is one of the quickest wins you can hand them.
Time it, but keep it calm
Set three minutes and see how far your child gets, then try to beat it on a later sheet with the same accuracy. Because each sheet is new, the comparison is fair. Stop the timing entirely if it produces anxiety, since a stressed child practices worse and the point here is fluency, not pressure.
A tip worth knowing
Encourage kids to hunt for pairs that make 10 (1+9, 2+8, 3+7, 4+6, 5+5) to speed up addition facts.
Printing this sheet
Press Print this sheet and the worksheet prints alone on a single portrait page, sized for US Letter or A4. Problems are laid out in two columns with a ruled answer line and enough space between rows for a pencil, rather than being squeezed together. Print with answers hidden for your child, then use Show answers and print once more if you want a key to mark against.
Frequently asked questions
Is it a problem if my child still counts on their fingers?
Not at first. Fingers are a reasonable way to work out a fact that is not yet known, and most children pass through that stage. What you want to see over a few months is the counting gradually being replaced by instant recall for the common facts. If nothing shifts, focus on the pairs that make ten.
Why does the worksheet change every time?
So practice cannot turn into memorizing one particular page. Twenty new problems are generated on each visit, which means a child who does the sheet three times in a week has genuinely practiced sixty problems. It also means you never need to hunt for another worksheet once these become easy.
Can I print an answer key?
Yes. Use the Show answers button before printing and the answers appear on the sheet, which gives you a key to mark against. Print once with the answers hidden for your child and once with them showing for yourself, since both versions come from the same set of problems.
