Subtraction within 10: a worked example (9 − 4)
- Start at 9.
- Count back 4: 8, 7, 6, 5.
- You land on 5, so 9 − 4 = 5. Check: 5 + 4 = 9.
What each part practices
- Part A (questions 1–27): Facts from 2 − 0 up to 10 − 10, mixed so that easy and harder facts alternate. Good for checking which facts are already quick.
- Part B (28–36): Ten frames with some counters crossed out in red. Your child writes the subtraction the picture shows, such as 8 − 3 = 5.
- Part C (37–45): Missing numbers like 8 − ___ = 5 and ___ − 4 = 1. These link subtraction to addition and to number bonds.
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
Give your child ten small toys for the first row. They take away the second number and count what is left, then try a row without the toys. 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
- Counting the start number as the first step back: 9, 8, 7, 6 gives 6.
- Taking the smaller number from the bigger one when the question is written the other way round.
What to practice before and after subtraction within 10
- Before: addition word problems. If this sheet is a struggle, go back a step.
- After: number line subtraction, once this one is mostly right.
- Learn it first: the subtraction within 10 lesson and the subtraction chart.
