2-digit subtraction with regrouping: a worked example (52 − 27)
52 − 27 ──── 25
- Ones: 2 is less than 7, so trade 1 ten: 12 − 7 = 5.
- Tens: 5 tens became 4 tens, and 4 − 2 = 2.
- The answer is 25. Check: 25 + 27 = 52.
What each part practices
- Part A (questions 1–20): Column subtractions where the top ones digit is always smaller, so a ten must be traded every time. Numbers stay below 100.
- Part B (21–40): Twenty more, including tens numbers like 40 − 23 where the top ones digit is 0. Your child checks two answers by adding.
The answer key on the last page lists every answer in order, so a grown-up or an older child can mark the sheet in a couple of minutes.
How to use it at home and in class
At home
Ask your child to check two answers on each page by adding. If the sum is the top number, the answer is right. Ten problems a day works better than a whole sheet at once. Mark them together with the answer key, then ask your child to explain one they got wrong: finding the mistake themselves is where the learning happens.
In class
Use the first row as a warm-up, a full page for independent practice, or five questions as an exit ticket. For a retake or a second group, make a new version with the test maker so every child gets different numbers.
Mistakes to watch for
- Taking the smaller digit from the bigger one: 7 − 2 = 5 gives 35.
- Making 12 ones but forgetting to cross out the ten.
What to practice before and after 2-digit subtraction with regrouping
- Before: 2-digit subtraction. If this sheet is a struggle, go back a step.
- After: 3-digit subtraction, once this one is mostly right.
- Learn it first: the 2-digit subtraction with regrouping lesson and the place value chart.
