Number Bonds to 10 Worksheets

Using this page

Missing number questions for the pairs that make 10: 7 + ? = 10, ? + 4 = 10 and 10 − 3 = ?. The Common Core asks kindergarten children to find the number that makes 10 for any number from 1 to 9, and number bonds to ten are the key to the 'make ten' strategy for harder addition and subtraction. Suits around Foundation and Year 1 in Australia and Kindergarten in the US (Common Core K.OA.A.4), 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

7 + ? = 10. Seven and how many more make ten? Show 7 on a ten frame: three squares are empty, so 7 + 3 = 10. The same bond gives 3 + 7 = 10, 10 − 7 = 3 and 10 − 3 = 7.

Common mistakes

Adding the two numbers shown, so 7 + ? = 10 is answered 17. Read the question as 'what goes in the gap'.

Answering 10 − 3 = ? with 13. Point to the minus sign before answering.

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

What is a number bond?
A number bond is a pair of numbers that join to make a total, such as 6 and 4 making 10. Knowing all the pairs for 10 by heart makes later maths much easier.

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.
