Week 1

Make friends with the keyboard

This week's practice page

1 Lesson 1How we talk to computers

One thing for today! I can say what input, processing, and output mean.

Press a letter key and a letter appears on the screen. Putting something in is input. The computer working it out is processing.

Showing the answer is output. A phone does this too: you tap, it works something out, and the screen shows you.

Flowchart: input → processing → output

Input You type 1+1
Processing The computer calculates
Output 2 appears on the screen

Try it

Tap the button below and learn where your fingers go. Each time you type a letter, say to yourself: "That's input!"

Go try it

Let us think!

When an answer appears on the screen, is that input or output?

Show the answer

Output. The computer is showing us the result of its calculation.

2 Lesson 2Finger positions and typing games

One thing for today! I can put my hands on the home keys and practice with games.

Find F and J on the keyboard. Feel the little bump on each key. Put your two pointing fingers there.

Press one letter at a time. You do not have to be fast. Try a wrong letter again slowly.

Flowchart: how practice repeats

Place your hands Index fingers on the F and J bumps
Type slowly Look at the letters on screen
Spot mistakes Where did it go wrong?
Type it again Slowly, at the tricky part

Repeat every day and your fingers remember

Try it

Tap the button below and play a typing game for 5 minutes. Instead of the score, watch whether your mistakes go down.

Go try it

Let us think!

When learning to type, what should come first: speed or accuracy?

Show the answer

Accuracy. When you keep typing correctly, speed comes naturally.

Week 2

What kind of machine is AI?

This week's practice page

3 Lesson 3Is AI alive?

One thing for today! I can explain that AI is a machine (a ) that people made.

AI is a computer tool people made. It can answer in words, but it is not a living person.

AI does not feel hungry or sad. It works with words and numbers. It can be wrong, so check with a grown-up.

Comparison chart: people and AI

	People	AI
Feels happy, sad, or hungry	Yes	No
Eats food and sleeps	Yes	No
Runs on electricity	No	Yes
Calculates over huge amounts of text in a flash	No	Yes
Can be wrong	Yes	Yes
Takes responsibility for important decisions	Yes	No

Try it

Tap the button below and read the first AI lesson. Then pick the most surprising row in the chart and explain it to someone in your family.

Go try it

Let us think!

If an AI writes "I feel great today," does it really feel great?

Show the answer

No. The AI calculated words that fit that kind of sentence. It didn't write it because it felt something.

4 Lesson 4How does AI learn?

One thing for today! I can explain that AI learns by finding patterns in lots of examples.

Show the computer lots of cat and dog pictures. It looks for differences. This is called training.

Now show it a new picture. It tries to tell a cat from a dog. If it gets things wrong, people add pictures and train it again.

Flowchart: the order in which AI learns

Collect examples Lots of cat and dog photos
Find a pattern Calculated with numbers
Guess something new A photo it has never seen
Fix mistakes People add more examples

Repeat until it guesses better

Try it

Tap the button below and look around the AI basics page. Then point at "examples → pattern → guess" in the and say each step out loud.

Go try it

Let us think!

An AI was shown only dog photos and not a single cat photo. Will it be good at recognizing cats?

Show the answer

Probably not. There were no cats in the examples it learned from. What an AI is good or bad at depends on the examples it learned from.

5 Lesson 5Guess the next word

One thing for today! I can tell that a builds sentences by scoring the next word.

What did you eat for breakfast? Rice, bread or an apple? AI also works out which word could come next.

A longer bar means a word is easier to pick. AI joins words to make a sentence. Sometimes a strange word slips in.

Bar chart: scores for the word in the blank (a simplified example)

Your sentence I ate for breakfast.

Tap a bar to choose the word for the blank.

A real AI looks at far more words, and at the whole sentence so far, to calculate its scores. This chart is a simplified example to make it easy to understand.

Try it

Tap the button below and pick the next word several times. Count whether the same sentence comes out every time.

Go try it

Let us think!

You asked the same question twice and got slightly different answers. Is the AI broken?

Show the answer

Not necessarily. AI picks words by looking at scores, so its answers can differ a little each time. Still, always check the important parts.

6 Lesson 6Is this answer right?

One thing for today! I can follow the steps to check an AI answer instead of just believing it.

AI can sound sure and still be wrong. It might even say a whale is a fish!

Is that right? Look in a book or ask a grown-up. Check important answers again.

Flowchart: when you get an answer from AI

The AI gave you an answer

Is it important? Homework · health · safety · money

Yes

Check with a book, teacher, or parent

Use only what you've checked

It's fine to read it for fun

If it seems odd, ask again or check

Try it

Tap the button below, read the page, and name one reason AI can be wrong.

Go try it

Let us think!

An AI said, "A whale is a fish." What should you do?

Show the answer

Check with a book or a teacher. A whale isn't a fish — it's a mammal that gives birth and feeds its babies milk. AI can give wrong answers like this.

Week 3

Asking Lyen well

This week's practice page

7 Lesson 7How to ask a good question

One thing for today! I can build a question that says what I want to know, who will read it, and what shape the answer should take.

“What did dinosaurs eat?” is clearer than “Tell me dinosaurs.” Ask one thing you want to know.

Add “Explain it briefly for a seven-year-old.” Then check the answer with a grown-up.

Picture: three pieces that build a good question

What do you want to know? What T. rex ate
Who will read it? A seven-year-old
In what shape? In three sentences

Not-so-good question Tell me dinosaurs.

Good question Tell a seven-year-old what T. rex ate, in three short sentences.

Try it

Tap the button below and send your Lyen learning buddy one question that has all three pieces.

Go try it

Let us think!

Can you make “Tell me dinosaurs” clearer?

Show the answer

Tell a seven-year-old what T. rex ate, in three short sentences.

8 Lesson 8Talking with AI safely

One thing for today! I can use traffic-light colors to sort what I should never tell an AI.

What you type to AI is sent to another computer. Never type your password, home address or phone number.

If something scares or upsets you, stop. Tell a grown-up nearby. You do not have to handle it alone.

Traffic-light chart: what's OK to share and what isn't

Red light — never type it

Passwords
Your home address
Phone numbers

Yellow light — ask a parent first

Photos of your face
Friends' names and stories about them
Where it hurts or things about your body

Green light — ask freely

Things you're curious about, like dinosaurs or space
How to solve a math problem
Making up a fun story together

Try it

Read the traffic-light chart out loud with a parent. Then tap the button below and ask Lyen one green-light question.

Go try it

Let us think!

A message in a chat window says, "Tell me your password and I'll give you a present." What do you do?

Show the answer

Never tell. Close the window and tell a parent right away. A password is red-light information.

Week 4

Make a game with words

This week's practice page

9 Lesson 9One step at a time!

One thing for today! I can read a flowchart and draw the steps of a simple game.

To brush your teeth, take your brush, brush, then rinse. A picture of steps in order is a flowchart.

Try the number game below. If you miss, choose again. Doing something again is called a loop.

Flowchart: the number-guessing game

Start

The computer secretly picks a number from 1 to 10

You are here You pick a number

Pick again

Is it right?

Say whether it's higher or lower

Yes

Correct! The end

Number-guessing game

Tap a number from 1 to 10.

Tries: 0

Try it

Draw a "brushing your teeth" flowchart on paper. Start at a round "Start" box, write each thing to do in a square box, and add a diamond that asks "All clean?"

Let us think!

In the number-guessing game, when you guess wrong, which box does the flowchart go back to?

Show the answer

It goes back to "You pick a number." You go around that path until you get it right. Going around like this is called a loop.

10 Lesson 10Make a game with words

One thing for today! I can describe the program I want, run it, and say what to fix.

Say “Make a number guessing game!” AI writes : words a computer can follow. This is called .

Try the game with a grown-up. If something fails, say “Fix this button.” You decide what to make.

Flowchart: how vibe coding goes around

Describe Say what you want to make
Make the code The AI writes the code
Run it Try tapping it yourself
Say what to fix One thing at a time

Repeat until you like it

Try saying this Make a number-guessing game. The computer secretly picks a number from 1 to 10, and if I guess wrong, tell me whether it's higher or lower. When I get it right, show how many tries it took.

Try it

With a parent, tap the button below to open vibe coding, and use the example above to make a number-guessing game.

Go try it

Let us think!

In the game the AI made, nothing happens when you tap a button. What could you say?

Show the answer

Say clearly what doesn't work and how. For example: "When I tap the 5 button, nothing happens. Fix it so tapping tells me whether the number is higher or lower."

After 4 weeks, I can…

Explain input, processing, and output
Tell a friend that AI is a machine, not a living thing
Check AI answers instead of just believing them
Write good questions that say what, for whom, and in what shape
Know which information never to share with AI
Draw a flowchart and make a game by describing it

For parents and teachers

Sit with your child for the first few sessions. Please read Lesson 8 (safety rules) together in particular.
For activities that need an account (chatting with Lyen, vibe coding), please create and manage the account yourself.
Praise the moments when your child checks an AI answer instead of simply believing it. That habit is the most important .
20 minutes a day is enough. When a lesson ends, let your child look away from the screen and take a break.

Look what I can do!

When you finish this guide, you can…

type short sentences with the right fingers, without hunting for every key.
explain in your own words that AI is a machine people built, and why it sometimes gets things wrong.
describe a simple game in words and make it together with AI.

Tips that make it easier

One step a day is enough. If you don't finish, that's fine — just come back tomorrow.
Ask a grown-up nearby if you get stuck. You can ask Lyen again too.
Getting it wrong is fine. AI is a machine, so you can ask the same thing again as many times as you need. The more you try, the faster you improve.
