Using this page
Two-digit subtractions such as 86 − 43, where each digit on top is at least as big as the one below, so no trading is needed. Children practise lining up tens and ones and subtracting each column, ready for the harder sheets where a ten has to be traded. Suits around Year 2 in Australia and Grade 2 in the US (Common Core 2.NBT.B.5), 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
86 − 43. Ones: 6 − 3 = 3. Tens: 8 tens − 4 tens = 4 tens. So 86 − 43 = 43. Check with addition: 43 + 43 = 86.
Common mistakes
Subtracting the tens digit of one number from the ones digit of the other. Keep tens under tens.
Forgetting to check. Adding the answer to the number taken away should give the top number.
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
Why do some answers have one digit?
When the tens digits are the same, as in 47 − 42, the tens cancel and the answer is a one-digit number, 5.
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.
