Addition Within 10 Worksheets

Using this page

Every question adds two numbers whose total is 10 or less, such as 4 + 5 or 7 + 3. These are the facts children meet first, usually with counters, fingers or a ten frame, and they are the base for everything that follows: making ten, adding within 20 and later column addition. A fresh sheet each day keeps practice short and stops children remembering the page instead of the facts. Suits around Foundation and Year 1 in Australia and Kindergarten and Grade 1 in the US (Common Core K.OA.A.2), but use whatever level fits the child.

Tips

• Keep sessions short: one sheet of 10 to 20 questions a day beats a long session once a week.
• Mark the sheet together with the answer key and talk about the mistakes; each one shows what to practise next.
• Move to the next sheet when a child gets almost every question right without counting on fingers.
• Where it is offered, use the column layout for written methods and the across layout for mental strategies.

Worked example

6 + 3. Start with the bigger number, 6, and count on three more: 7, 8, 9. So 6 + 3 = 9. Children who know that 6 + 4 = 10 can also see that 6 + 3 is one less than 10. Counting on from the larger number is quicker and less error-prone than counting both groups from one.

Common mistakes

Counting the starting number again, so 6 + 3 becomes 8 (saying 6, 7, 8). Count on from the next number.

Mixing up + and − when both kinds of sheet are in use. Ask children to circle the sign before they start.

How to use this generator

Choose the options above the sheet: the number of questions and the settings for this kind of worksheet. Every change makes a new sheet straight away, and New worksheet gives a different set of questions with the same settings.

Each sheet has a worksheet number printed at the top. Type the same number later, or keep the page link, to print exactly the same questions and answer key again. Leave Answer key page ticked to print the answers on a second page, then press Print. Every printed page carries the makekite logo and web address.

Common questions

Should children use their fingers?
Yes, at first. Fingers and counters show what adding means. As facts become familiar, encourage counting on from the bigger number, then recalling the answer straight away.

How many questions should a child do?
Ten to twenty is plenty for daily practice. The 100-question drill sheet is for short timed practice once or twice a week.

Can I print the same worksheet again?
Yes. Note the worksheet number printed at the top, or keep the link in your browser's address bar, which ends with that number. Entering it later gives the same questions and answers.

Is it free?
Yes. There is no sign-up, and nothing you choose is sent anywhere: the sheets are made in your browser.
