Apostrophe Detective Quiz is a free printable quiz for Year 4 (ages 8 to 9). Children crack seven cases by choosing the right answer from three. They work with apostrophes that show who owns something and apostrophes that stand in for missing letters. It takes about 10 to 20 minutes and needs only a pencil. Page 2 gives the grown up notes and the answers.
It comes from the Mini Minds Hub, the free library of printables from Jaques of London, the British games and toy company that has been making games for families since 1795. Print both pages, give page 1 to your child and keep page 2 for yourself. Black and white printing works well.
What is on the sheet
The sheet is a quiz with seven cases. Each case is a multiple choice question with three answers, and children circle the one they think is right. Some cases ask them to match an apostrophe to one owner or to more than one owner. Others ask about short forms of words, or ask them to pick the correct sentence or spot the one that uses an apostrophe wrongly.
- Which one shows ONE dog owning a bone?
- Which one shows TWO dogs owning a ball?
- What is "don't" short for?
- Which sentence is correct?
- Which sentence uses an apostrophe wrongly?
- What is "they're" short for?
- Which one shows THREE girls owning a tent?
Worked example: choosing where the apostrophe goes
Which one shows TWO rabbits owning a hutch? A) the rabbit's hutch B) the rabbits' hutch C) the rabbits hutch
This question is not on the sheet. It shows two ways children can work out where an apostrophe belongs.
Method 1: count the owners, then place the mark- Ask: how many owners are there? Here there are two rabbits.
- Write the owner word on its own: rabbits. It already ends in s.
- Put the apostrophe after that s, then write the thing owned: rabbits' hutch.
- Turn the phrase round: the hutch of the rabbits.
- Find the owner in that phrase: the rabbits. There is more than one.
- Write the owner word, add the apostrophe after the s, then add hutch.
What does an apostrophe actually do?
The apostrophe is a small mark with two main jobs. In a contraction, it shows where letters have been left out when two words are squashed into one, as in isn't. In possession, it shows that something belongs to someone, as in the cat's basket. Both jobs use the same mark, so children need to ask which job it is doing before they decide where it goes.
For possession, the position of the apostrophe tells the reader how many owners there are. It goes before the s for one owner. It goes after the s for a plural owner that already ends in s, such as two cats. Some plurals do not end in s, such as children, and these take an apostrophe and then s. In Years 3 and 4, children learn to choose the right place with confidence.

Ideas to keep in mind while helping
- Two jobs, one markAn apostrophe can show missing letters or show belonging. Before choosing an answer, ask your child which job the apostrophe is doing in that case.
- Find the owner firstFor possession, pick out the owner word and ask if it means one or more than one. That decides where the apostrophe goes.
- Missing letters sit under the markIn a contraction, the apostrophe takes the place of the letters that have gone. Say the two full words aloud to hear what was squashed.
- Not every plural ends in sWords such as children and men are plural but do not end in s. When they own something, the apostrophe goes before an added s.
Key words
- ApostropheA small mark that looks like a floating comma. It shows missing letters or shows that something belongs to someone.
- ContractionA short word made by joining two words and leaving out some letters. The apostrophe marks the gap.
- PossessionWhen something belongs to someone. An apostrophe can show this.
- SingularJust one. One cat is singular.
- PluralMore than one. Three cats is plural.
- OwnerThe person, animal or group that something belongs to.
How to use it
- Print both pages. Page 1 is for your child. Keep page 2, which has the notes and answers.
- Read each case aloud. Ask your child to say what the question is really asking before they choose.
- Let them circle one answer for each case. Ask them to point at the apostrophe and say what it is doing.
- Check together using page 2. Talk about any wrong answers and why the apostrophe sits where it does.
- Come back another day and try the cases that felt tricky. Repeating a familiar sheet builds confidence.
Help, stretch and game ideas
If it feels too hard
Start with the cases about owners. Ask: how many owners are there? Say the owner word on its own. One owner means the apostrophe goes before the s. Many owners that end in s means it goes after the s. Do a few cases now and a few later.
To stretch confident children
Write a short detective report of five sentences. Include at least one contraction, one sentence with a single owner and one with a group of owners. Swap reports with someone else and check every apostrophe, then explain each choice aloud.
Make it a game
Play Apostrophe Thief. One player writes a sentence and leaves out every apostrophe. The other player puts them back and says why each one goes where it does. Score a point for each correct apostrophe. Swap roles after each round.
Mistakes to watch for
Watch forA child puts an apostrophe in every word that ends in s, even when nothing is owned and no letters are missing.
Try thisAsk two questions: does something belong to someone here, and are any letters missing? If both answers are no, the word needs no apostrophe.
Watch forA child puts the apostrophe in the wrong place in a contraction, such as in the middle of the second word.
Try thisSay the two full words aloud. Cross out the letters that disappear. Put the apostrophe exactly where those letters were.
Watch forA child mixes up one owner and many owners and puts the apostrophe on the wrong side of the s.
Try thisWrite the owner word on its own first and count it. One owner, apostrophe then s. Many owners ending in s, apostrophe after the s.
Talk about it
- How can you tell if an apostrophe is showing missing letters or showing belonging?
- Why does it matter where the apostrophe goes? What changes for the reader?
- Which case did you find trickiest, and what helped you decide?
- Can you think of a word where the apostrophe would sit in a different place if there were more owners?
- Why might a writer use a contraction instead of two full words?
- How would you explain apostrophes to a younger child?
Take it off the page
Apostrophe hunt
Look through a favourite book or a cereal box for apostrophes. Sort them into two lists: missing letters and belonging. Talk about any that are hard to place.
Owner labels
Draw a quick picture of a few pets or toys. Write labels such as the owner's name and the thing owned. Then draw more owners and change the labels.
Squash and stretch
Write pairs of words on paper strips. Squash two strips together into a contraction, adding an apostrophe card where letters go missing. Then stretch it back into two words.
Who it is for
Parents
Sit with your child for the first case, then let them lead. Ten to fifteen minutes is plenty. Ask them to explain each choice aloud, and praise clear reasons as much as right answers.
Teachers
Use it as a starter, a plenary after teaching apostrophes, or an early finisher task. Page 2 has answers and support and stretch ideas, so it suits mixed ability groups. It also works well as a team quiz.
Home educators
Print it as one part of a wider English plan. It pairs well with writing a short story or letter, where children can use apostrophes in their own work. Reuse it later for brothers, sisters or revision.
Where this fits in learning
Before this sheet, children learn to use capital letters and full stops, and to form plurals. In Year 2 they meet apostrophes for contractions and for a single owner, so this sheet builds on that first step.
After this sheet, children move on to using apostrophes confidently in their own writing and checking it for errors. In Years 5 and 6 they widen their punctuation with commas, brackets and other marks, so secure apostrophe use is a useful foundation.
Questions parents and teachers ask
- What age is Apostrophe Detective Quiz for?
It is written for Year 4, which is ages 8 to 9, in Key Stage 2. Younger children may enjoy it with help, and older children can use it as quick revision or a warm up.
- What will children practise?
They practise apostrophes for contractions and for singular and plural possession. This matches what the National Curriculum for England sets out for Years 3 and 4. They also practise reading carefully and explaining their choices.
- How long does it take?
Most children finish page 1 in 10 to 20 minutes. You can split it over two sittings or do a few cases at a time. Page 2 has ideas for making it shorter or longer.
- What if my child finds it too hard?
Start with the cases about owners and ask how many owners there are. One owner means the apostrophe goes before the s. Many owners ending in s means after the s. Leave the rest for another day.
- Do I need to print in colour?
No. The quiz prints clearly in black and white on plain A4 paper. Colour is not needed to answer any of the cases, so you can save ink.
- Can teachers use it in class?
Yes. It works as a starter, plenary, early finisher task, homework or table activity. It needs no preparation beyond printing, and page 2 includes answers plus support and stretch ideas for mixed groups.
- Is it free, and is it screen free?
Yes to both. It is free to print for home and classroom use. It needs only paper and a pencil, so it suits quiet time, rainy days and school holidays.
