Conjunction Chain Reaction is a free printable grammar worksheet for Year 3 (ages 7 to 8). Children fill the gaps to set off a silly chain of events, unscramble three words, then decide whether each grammar statement is true or false. It needs only a pencil, and page 2 gives the grown up notes, help ideas and a stretch task.
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
Children start with a word bank, which is best read aloud before anyone picks up a pencil. They then use it to fill the gaps in a silly story where one event sets off the next. After that they unscramble three words, and finish by reading grammar statements and deciding if each one is true or false. The sheet mixes choosing, spelling and checking in one short activity.

Say it aloud
Hearing a sentence makes it easier to notice when a joining word fits and when it does not. Let your child read each gap sentence aloud before they write.
Test a swap
If a child is unsure, ask them to try a different word from the bank in the same gap. Does the sentence still make sense? Does it say something different?
Look at the whole sentence
The story only works if each part leads to the next. Ask your child to read the sentence from the start to the end before they decide.
Check the punctuation last
Once the gaps are filled, read the whole chain again. Look for places where the reader needs a pause and check that the commas help.
What is a conjunction?
A conjunction is a word that joins words, phrases or clauses. It shows how two ideas are connected. Some conjunctions link ideas that happen at different times. Some give a reason or a result. Some add a choice, or show that two ideas pull in different directions. Choosing the right one changes what a sentence means, which is why grammar practice is about thinking, not only filling gaps.
A chain reaction is a good setting for this skill because each event causes the next one. Children can see why one joining word makes sense and another does not. The silly tone helps too. Children are more willing to read aloud, laugh at a strange sentence and then fix it. Checking commas at the end teaches them to proofread their own writing.

Grammar ideas for grown ups
- Joining ideasConjunctions let children build longer sentences from shorter ones. A sentence with a joining word can say more than two separate short sentences.
- Cause and effectA chain reaction story depends on one thing leading to another. Ask your child how the joining word shows that link.
- Use your earReading aloud is the quickest check. A word that does not fit usually sounds wrong before a child can explain why.
- Commas help readersCommas guide the reader through a sentence. Ask your child where their voice naturally pauses, then look at whether punctuation supports it.
Key words
- ConjunctionA joining word. It links words or parts of a sentence together.
- SentenceA group of words that makes complete sense. It starts with a capital letter and ends with a full stop, question mark or exclamation mark.
- ClauseA group of words with a doer and a doing word. It is a part of a sentence.
- CommaA punctuation mark that helps a reader pause or keeps parts of a sentence apart.
- UnscramblePut mixed up letters back in the right order to make a word.
- True or falseA statement is true if it is correct. It is false if it is not correct.
How to use it
- Print both pages. Page 1 is for your child. Keep page 2, which has the notes for you.
- Read the word bank aloud together. Ask your child to say each word in a sentence of their own if they can.
- Let your child fill the story gaps, unscramble the three words, then decide if each grammar statement is true or false.
- Work through the first go together and talk about each choice. Ask, "Why does that word fit here?"
- Check against the notes on page 2. Come back another day, because repeating a familiar activity builds confidence.
Help, stretch and game ideas
If it feels too hard
Read each gap sentence aloud with every word from the bank, one at a time. Ask which one sounds right and makes sense. Cross out each word as it is used. Fill in the easiest gaps first, then return to the harder ones.
To stretch confident children
Write your own two sentence chain reaction. Use a different conjunction in each sentence and check your punctuation carefully. Then read it aloud to a grown up and ask them to spot the joining words.
Make it a game
Write some conjunctions on small slips of paper and fold them. Take turns to pick one and add a new silly sentence to the chain that starts with it. Read the whole chain aloud each time. Stop when the chain gets too silly to follow.
Mistakes to watch for
Watch forA child chooses a funny word that does not make sense in the sentence.
Try thisRead the whole sentence aloud with that word. Ask, "Does this say what we mean?" Then try another word from the bank.
Watch forA child misspells a conjunction when writing it in a gap.
Try thisLook at the word in the bank, cover it, write it from memory, then check. Say the word in small chunks while writing.
Watch forA child puts commas in everywhere, or nowhere.
Try thisRead the sentence aloud and listen for natural pauses. Check one comma at a time and ask what it is helping the reader to do.
Watch forA child rushes the true or false statements and guesses.
Try thisAsk them to make up their own sentence to test the statement. Then decide if it is true or false and explain why.
Talk about it
- Which joining word did you find easiest to choose, and why?
- Can you think of a sentence where changing the joining word changes the meaning?
- Why is it helpful to read a sentence aloud before you write it?
- What makes a chain reaction story funny?
- How did you decide whether a statement was true or false?
- What would happen next in the chain if we kept going?
Take it off the page
Comic strip chain
Fold a piece of paper into boxes. Draw a silly chain of events, one in each box. Write a sentence under each picture and join them with conjunctions.
Real chain reaction
With a grown up, line up safe objects such as dominoes or soft toys so that one knocks the next. Describe what happens using joining words.
Spelling practice
Pick the conjunctions your child found trickiest. Practise them with look, say, cover, write and check. Keep it quick and calm.
Who it is for
Parents
Sit beside your child for the first go, then let them lead. Read the word bank aloud together. If they get stuck, ask them to read the sentence aloud and listen. Praise careful thinking, not only correct answers.
Teachers
Use it as a starter, plenary, early finisher task or table activity after teaching conjunctions. It needs no preparation beyond printing. Page 2 gives support and stretch ideas, so you can adapt it for mixed ability groups.
Home educators
Print it as part of a wider English plan. It pairs well with reading aloud, story writing and everyday talk. Because the sheet is free to print, you can use it again with brothers and sisters or as a quick revision task.
Where this fits
Before Year 3, children learn to join short sentences using a small set of common joining words. They learn that a sentence can say more than one thing. They also practise capital letters and full stops so that their sentences are clear.
After this, children widen the range of sentences they write. They use a greater variety of joining words, and add adverbs and other phrases to give more detail. They also use punctuation inside sentences, including commas, with more control. This sheet builds the habit of choosing words carefully and checking work.
Questions parents and teachers ask
- What age is Conjunction Chain Reaction for?
It is written for Year 3 (ages 7 to 8), in Key Stage 2. Some Year 2 children may enjoy it with support, and older children can use it as quick revision.
- What will children practise?
Children practise choosing and spelling conjunctions and checking sentence punctuation. It is an English grammar activity that also builds careful reading, because the gaps only make sense when the whole sentence is read.
- How do I use it?
Read the word bank aloud first. Children then fill the story gaps, unscramble three words and decide if each grammar statement is true or false. Work through it together the first time and talk about each choice.
- What if it feels too hard?
Read each gap sentence aloud with every word from the bank and ask which one sounds right and makes sense. Start with the easiest gaps and come back to the rest. Stopping and returning another day is fine.
- How long does it take?
It depends on the child. There is no set time. Children can work at their own pace, and you can stop after any part and return later. Working together the first time often helps.
- Can teachers use it in class?
Yes. Teachers can use it as a starter, plenary, early finisher task, homework or table activity. It needs no preparation beyond printing, and page 2 has help and stretch ideas for mixed ability groups.
- Is it free, and do I need colour?
Yes, it is free to print for home and classroom use. No colour is needed. It prints well in black and white on plain A4 paper, and it needs only a pencil, so it is screen free.
