Seven Find-the-Mistake Games to Play at Home (No Worksheets)

Proofreading worksheets have a reputation problem. Children see a page of sentences with “find and correct the mistake” at the top and their energy drops before they start.

Yet the same children love catching an adult out. Make a deliberate mistake while reading a bedtime story and watch how fast they pounce. Finding mistakes is naturally fun — it’s the worksheet that isn’t.

Here are seven games that practise exactly the same skill, with no printing and almost no preparation. Each takes five to ten minutes and works from P1 to P6 with small adjustments.

Before you start: two rules for every game

1. One mistake at a time. Each sentence should have exactly one thing wrong, with one clear correction. Two mistakes in one sentence frustrate younger children.
2. No red for wrong guesses. A wrong guess means your child is looking — that’s the habit you want. Celebrate the finds; ignore the misses or just say “not that one, keep looking”.

1. Teacher swap

How it works: you say or write a sentence with one mistake; your child plays the teacher and corrects you. Then they make a sentence with a mistake for you to find.

Why it works: children love being the teacher, and inventing a mistake means they have to know the rule. When they plant two cat for you, they’re practising plurals.

Adjust by grade: P1 — capitals and full stops (my cat is black). P2–P3 — is / are, -s on verbs, past tense. P4–P6 — their / there, more bigger, has went.

2. Spot the slip (bedtime-story version)

How it works: while reading a story aloud, change one word on purpose every page or two: The three bear was hungry. Your child shouts “slip!” and gives the correct word.

Why it works: it trains the ear, which is often faster than the eye at catching grammar mistakes. It also fits into reading time you already have.

Tip: keep a count. “Tonight I slipped five times — can you catch all five?”

3. Beat the clock

How it works: write three sentences, each with one mistake. Your child gets one point for finding each mistake, one for fixing it, and a bonus if they finish before a timer (a minute or two). A wrong guess costs a point — but the score never goes below zero.

Why it works: a little time pressure adds excitement, and the score makes progress visible. This is the same scoring we use in ProofreadEasy: a star for each find and each fix, a bonus under par, and wrong taps that cost one star but never turn red.

Careful: for anxious children, drop the timer and keep the points.

4. Sentence surgery

How it works: write a correct sentence on strips of paper, one word per strip. While your child looks away, swap one word for a wrong version (went → goed, Monday → monday) or add a word (play the football). They find the “sick” word and operate.

Why it works: physically handling words makes them look at each one separately — exactly what proofreading needs. Great for kinaesthetic learners and younger children.

5. Mistake bingo

How it works: make a bingo card with mistake types instead of numbers: capital letter, full stop, is/are, past tense, plural, their/there. Over a week, every time your child finds a mistake (in practice sentences, their own writing or your planted slips), they mark the type. A row wins a small reward.

Why it works: it teaches children to name the kind of mistake, which is what helps them find the next one. The eleven common types are listed in English proofreading by grade.

6. Two versions, one difference

How it works: write the same sentence twice, one correct and one with a mistake:

Yesterday we visited the zoo. Yesterday we visit the zoo.

Your child finds the difference and says which version is right — and why.

Why it works: comparison is easier than searching, so it’s a good starting point for children who find proofreading hard. Once they’re confident, move to single sentences with no correct version to compare.

7. The family detective notebook

How it works: keep a small notebook where your child records every mistake they catch, anywhere: in practice sentences, in their own homework, in the slips you plant. Each entry is the wrong version, the right version and a few words of “why”.

Why it works: over a few weeks the notebook shows patterns — maybe most entries are past tense, or capital letters. That tells you exactly what to practise next, and children are proud to see the list grow.

A week of games

If you want a simple plan, rotate through the games like this:

• Monday: Two versions, one difference (5 minutes)
• Tuesday: Spot the slip at bedtime (during reading)
• Wednesday: Teacher swap (5–10 minutes)
• Thursday: Sentence surgery (5–10 minutes)
• Friday: Beat the clock (5 minutes)
• Weekend: update the detective notebook and mistake bingo (5 minutes)

Repeat the same week for a month before changing it. Children like knowing what’s coming, and repeating the same games lets you see real progress in the scores and the notebook.

Keeping it going

• Short and frequent beats long and rare. Ten minutes three or four times a week is plenty.
• Stop while it’s fun. End on a success, even if it means an easy last sentence.
• Mix in the method. Games build motivation; a checking routine builds skill. The four-step routine slots into any of these games — and for upper primary, the passage routine.
• Need sentences? These 20 practice sentences with answers work for Teacher swap, Beat the clock and Two versions.

Frequently Asked Questions

What age are these games for?

All seven work from about age 6 (P1) to 12 (P6). Change the kind of mistake to fit the grade: capitals and full stops for P1, verb agreement and tenses for P2–P3, confusable words and comparatives for P4–P6.

My English isn’t strong. Can I still play these games?

Yes. Use sentences with known answers (from a worksheet, an answer key or an app), and let your child explain the correction to you. Explaining it is great practice for them.

How do I make sure my planted mistake has only one correct answer?

Change only one word, and choose changes with a single clear fix: a missing capital, is for are, a present verb in a sentence that starts with Yesterday. Avoid changes that could be corrected in two ways.

Do games really help with exam proofreading?

Games build the habit of looking at each word and naming the mistake type, which is the core skill in exam proofreading. Combine them with an occasional practice passage in the exam format so your child is familiar with how the question looks.

What if my child gets upset when they can’t find the mistake?

Give a hint about where to look (“check the last word”) rather than the answer, and make the next sentence easier. Comparing two versions (game 6) is the gentlest starting point.
