1. Story — Text-Based (Day 1-2: Imagination Studio)

Read this AI Pre-Literacy story with NO pictures first. Child becomes illustrator.

The vacuum arrives on a Monday. A round white disc, low to the floor, one soft blue light on top.

Lina is seven. Omar is eight. Pip stands by the doorway, tall and humanoid, blue light soft at the eyes.

Grandpa brings it in from the workshop. “It cleans by itself,” he says. “I want to see if it can.”

The vacuum has a dock — a small black plate under the coat rack. That is home.

When it wakes, it draws a map of the room in its head. A grid of tiny squares. Some squares free. Some squares blocked.

That is an Occupancy Grid — the room drawn as tiny squares, each one empty or filled.

The vacuum needs to know where it is on its own map. That is Localisation — knowing where you are on the map you drew.

It counts its own wheel turns. Each turn is a small step. That is Odometry — counting steps to guess how far you have moved.

And when the guess slides slowly wrong, that is Drift. The map says one thing. The floor says another.

On Tuesday, the vacuum pushes past the sofa. It has never been behind the sofa before. It marks a row of new squares.

That is a Frontier — the edge of the map, where the robot has not yet been.

Lina loves it. “Let it go everywhere,” she says. “Every room. Every day.”

Omar is not so sure. “It has only seen the living room,” he says.

“It’s fast,” says Lina. “It’s fast in here,” says Omar. Neither one smiles.

On Wednesday, the vacuum wakes. A soft blue dome of light spreads over its head — the map drawing itself in the air above it.

Lina stands at the edge of the room with her hands empty. Omar stands beside her with his hands empty. Pip stands at the doorway between them.

The vacuum sweeps past the sofa. It sweeps past the rug. New squares appear on its map with every pass.

Then it finds a small paper sail on the floor. Omar’s paper sail. From the boat he built with Grandpa, three summers ago.

The sail fell off the desk that morning. Omar did not see it fall. The vacuum sweeps it up.

The sail is torn. Not gone, but torn.

Omar holds the two pieces together. They do not meet anymore. Not quite.

That is the cost. Some things cannot be mended back exactly.

Nobody is angry. The room is very quiet.

Pip walks to the vacuum’s map. “Show me where the sail was found.”

The map shows a square under Omar’s desk. Then another. Then another. The sail was dragged through five squares before the vacuum stopped.

“It has a small feeler,” says Pip. “That is a Bump Sensor. It tells the vacuum it has touched something. But the sail is too light. The feeler does not feel it.”

Lina looks at the map. “It didn’t know it was pulling something.”

“It cannot know,” says Pip. “Not unless a person tells it where the small things live. That is a Forbidden Zone — a place a person has drawn that the robot must never enter.”

Omar draws a rectangle around his desk. He colours it in. He tapes it to the wall above the dock.

Now the vacuum will not go under the desk. It will go around.

But the vacuum still slides on its own map. In the upstairs hall, the drift grows. It turns too soon. It turns too late.

Lina and Omar put a small grey disc on the wall at the top of the stairs. That is a Beacon — a fixed mark the vacuum can find and use to know where it is.

The vacuum wakes on Thursday. It finds the beacon. Its map jumps back into place. The drift goes away.

On Friday, it cleans the upstairs hall. It cleans around the beacon. It stops at the top of the stairs, every time.

But it needs a rule for when to stop. When to give up and go home. Lina sets the number: twenty percent battery. Below twenty, the vacuum stops what it is doing and rolls back to the dock.

That is Recharge Behaviour — the rule for when to stop and go home to charge.

And it keeps a second map. Not of walls, but of dirt. Where the crumbs were. Where the sand was. Where the paper bits were found.

That is a Dirt Map — a picture of where the dirt was worst.

By Sunday, the living room and the upstairs hall are clean. Omar’s desk is a forbidden zone. The sail sits on a shelf, torn, taped back to the two pieces that used to be one.

Lina holds the map. Omar holds the two pieces of the sail. And Pip stands at the top of the stairs by the small grey beacon — blue light soft — watching the round white disc roll past the desk, past the beacon, and home.

2. Image 1 — Association Anchor (Day 3-4)

Top of Image 1 — This is what you just read, now you can see it.

The living room on the morning the vacuum wakes — the round white disc sits at the centre of the rug, low to the floor, one soft blue light on top, and above it a translucent blue dome of light spreads outward, drawing the room as a grid of tiny squares. Behind the sofa, a new row of squares glows faintly at the edge of the map — the frontier. Lina, age seven, in blue overalls and a yellow shirt with round glasses, stands at the left edge of the rug with her hands empty. Omar, age eight, in a green shirt and green glasses, stands at the right edge of the rug with his hands empty. Pip, humanoid and tall, stands at the doorway between them, blue light soft at the eyes. On the floor near the sofa: a small pile of colourful blocks and one small white paper sail, unnoticed, half under the desk. In the corner under the coat rack, the black docking plate waits.

3. What is the purpose of this Image 1?

Purpose: To ANCHOR what child imagined in Days 1-2 to a direct picture.

Direct resemblance to this AI Pre-Literacy story — the living room on the morning the vacuum wakes. The round white disc sits low to the floor with one soft blue light on top. Above it, a translucent blue dome spreads outward — the room being drawn as a grid of tiny squares. That is the Occupancy Grid. Behind the sofa, a row of new squares glows faintly at the edge of the map — that is the Frontier. Lina — age seven, blue overalls, yellow shirt, round glasses — stands at the left edge of the rug with her hands empty. Omar — age eight, green shirt, green glasses — stands at the right edge of the rug with his hands empty. Pip stands at the doorway between them, blue light soft at the eyes. On the floor near the sofa: the small pile of blocks, and half under the desk, one small white paper sail — the one that will be swept up. In the corner under the coat rack, the black docking plate waits.

Use Day 3-4: Point and name together — Where is the vacuum? Where is the blue dome of light, and what is it drawing? Where is the row of new squares behind the sofa? Where is Lina standing, and what is in her hands? Where is Omar standing, and what is in his hands? Where is Pip? Now look under the desk. What is that small white thing on the floor? That is the paper sail. The vacuum has not found it yet. Where is the docking plate? That is home — where the vacuum goes when it needs to charge.

6. Image 2 — Creator Prompt (Day 5: Imagination Studio)

This image is NOT in this AI Pre-Literacy story — this one is YOURS.

Blueprint view of the same living room, drawn from above — the round white vacuum sits at the centre, half-drawn, waiting for the child to decide where it should go next. On the floor beside it, drawn as a grid of tiny squares, is a blank occupancy map with three new squares marked but unnamed. Lina, age seven, in blue overalls and a yellow shirt with round glasses, holds up a small torch, its beam pointing at one unmarked corner of the map. Omar, age eight, in a green shirt and green glasses, holds up a magnifying glass, looking closely at one tiny square. Pip, humanoid and tall, stands between them with one hand on the map. On the wall above the docking plate, a blank rectangle is drawn for a forbidden zone, and beside it a small grey disc is pinned — a beacon still to be placed. Around them the ten vocabulary cards are pinned in a circle. On a shelf at the bottom of the page, the torn paper sail rests beside a roll of tape.

Purpose: To CREATE a new story — child becomes author.

Look at this picture together. You already know Lina and Omar and Pip. You know what happened when the vacuum learned the living room. Now this picture shows you something new — something that did not happen in the story.

Ask your child: Who is in this picture? Where are they? The round white vacuum is half-drawn — where should it go next? Lina is holding a torch — what is she pointing at? Omar is holding a magnifying glass — what is he looking for? Look at the map on the floor. There are three blank squares. What should go in each one? Where would you draw the Forbidden Zone — and why there? Where would you put the Beacon, and how would the vacuum use it? What rule would you set for Recharge Behaviour — how low should the battery go before the vacuum goes home?

Let your child tell you the story out loud. Do not correct it. There is no wrong answer.

Then, if they want to, they can draw it.
