Year 6 SPaG worksheet on commas that change the meaning: 10 SATs-style questions with answers. Free printable PDF.

3-page A4 PDF from the Tiger Shark Education question bank (Punctuation): two pages of questions (tick one) and an answer page. Example questions: Which sentence means that ALL the books were overdue? Tick one. / Which sentence shows the writer has only one cousin? Tick one.

Commas that change the meaning: a comma can completely change how a sentence is understood. ‘Let’s eat, Grandma’ and ‘Let’s eat Grandma’ mean very different things. Commas can show who is being addressed, separate items in a list, or mark extra information, and their position affects meaning. The SATs often ask pupils to explain the difference between two versions of a sentence.

Common mistakes and tips: Children often find it hard to explain the difference in words even when they can see it. Encourage them to read both sentences aloud, pausing at the commas, and describe what each one means. Drawing a quick picture of each meaning helps. Practising with funny examples makes the point memorable.

Quick example to try: compare ‘Most of the time travellers worry about their luggage’ with ‘Most of the time, travellers worry about their luggage’. Ask pupils to draw or describe what each sentence means, then write their own pair of sentences where a comma changes the meaning.

In the KS2 SATs, grammar and punctuation are tested in a separate paper of around 50 short questions, and this topic regularly appears. The questions on this sheet use the same styles as the test (circle, tick, underline, insert), so children practise the format as well as the knowledge.

Teaching ideas: model the first two questions together and talk through the reasoning, then let children complete the rest independently. Use the answers to group pupils for a follow-up session. For extra challenge, ask children to explain their answers in a full sentence using the correct grammatical terms.

Supporting all learners: for children who find grammar difficult, read the questions aloud and work through the first few together before they continue alone. Colour-coding word classes or clauses on mini whiteboards makes abstract ideas more concrete, and sorting word cards or building sentences from strips helps too. More confident pupils can write their own test-style questions for a partner, with the answers and a short explanation. Once each topic is secure, mix it with others, because the real test does not group questions by topic and pupils need to recognise what each question is asking them to do.
