Year 5 writing: The greenhouse message
Build a mystery whose clues lead to a fair ending.
Your writing task
Write a story in which a child notices a message on a greenhouse window. The message should lead to a small, surprising discovery. Explain the clues without making the ending appear by chance.
Plan before you write
- Who notices the message, and what are they doing there?
- Which two clues will help them understand it?
- What discovery makes the clues fit together?
Write on paper or in your own document. Try a first draft before reading the model responses.
An opening you can try
Only one pane of the greenhouse was covered in mist.
Use this opening or write your own. A useful opening gives your reader something to follow.
A small word bank
- peculiar
- Describing something strange or odd, unlike what you would usually expect.
- hunch
- A feeling that something is true, even without any proof.
- genuine
- Real, and exactly what it claims to be.
Choose a word only when its meaning fits. You do not need to use every word in the bank.

Compare three model responses
These are three ways to develop the same task. They are teaching examples, with notes linked to the English national curriculum. They are not exam grades or a prediction of a mark.
A starting point
Mina saw words on the greenhouse glass. They said, 'Look under the blue pot.' She wondered who had written them. Inside, most of the pots were brown, but one was blue.
Under it she found a small tin. A note inside explained that Grandad had saved seeds from her favourite flowers. She carried the tin to him and asked if they could plant them together.

most of the pots were brown
The unusual pot makes the instruction possible to follow.
Write for a reader and purpose
Grandad had saved seeds
The discovery answers the question raised by the message.
Try next: Give Mina a reason to recognise the flowers.
A more developed response
Only one pane was misty. Mina leaned closer and read the words pressed into it: 'Blue pot. Look below.' The handwriting sloped like Grandad's labels, but he was still in the kitchen.
She found the pot beside a tray of seedlings. Last summer, it had held the yellow flowers she picked for Mum. Beneath its saucer was a biscuit tin with a picture of the same flowers taped to the lid.
Inside lay three folded packets. Grandad had kept the seeds. Mina heard his footsteps on the path and turned, holding the tin carefully. "I thought we'd grow them again," he said. The greenhouse suddenly felt full of summer.

sloped like Grandad's labels
The handwriting is a clue to who left the message.
Organise related ideas
a picture of the same flowers
The pot and picture connect the discovery to Mina's memory, making the ending earned.
Try next: Explain why the message is visible only on that pane.
A further developed response
Only one pane of the greenhouse was covered in mist. Mina had come for the watering can, but the marks on the glass made her stop. 'Blue pot. Look below.' The letters leaned to the right, just like Grandad's plant labels.
A warm mug sat beneath the window. Grandad must have stood there earlier, leaving a message where his tea had steamed the cold glass. Mina smiled at the peculiar plan.
The blue pot was empty now. Last summer, its yellow flowers had filled Mum's birthday jar. Mina lifted the saucer and found a flat tin, wrapped with string. On the lid was a photograph of that jar. Her hunch was right.
Three seed packets waited inside, each carrying a careful handwritten label. Grandad appeared at the door with two small trowels. "A genuine treasure needs planting," he said. Mina took one trowel. This year, she decided, she would leave a message of her own.
Teaching notes
Choose useful details and words

The model explains the mist, closing a small gap in the mystery rather than ignoring it.
Organise related ideas
she would leave a message of her own
The ending grows from the original message and suggests Mina taking part next time.
Try next: Remove any detail that does not help the mystery or its ending.
Read back and improve
- Can the reader follow how each clue helps?
- Have you explained anything that might seem impossible?
- Check that dialogue moves the story forward.
