How to Teach AI to Kids

Almost all of this can be taught without a screen, and the unplugged version is better for younger children because the mechanism is visible instead of hidden behind a chat box.

Sorting, which is classification

Put a pile of mixed objects on the table. Ask your child to sort them and then to explain the rule they used. Now swap: you sort, they guess the rule.

That is what a classifier does. It is shown examples, works out a rule, and applies it to new things. Do it with buttons, leaves, socks, anything.

The interesting part is the failure. Introduce an object that does not fit the rule and watch what happens. That is exactly how these systems fail: confidently, by applying a rule to something it was not made for.

Training data, and where bias comes from

The best demonstration for children of about eight and up.

Ask them to teach you what a bird is by drawing five birds. Almost every child draws five small perching birds. Now show them a penguin and an ostrich and ask whether your new rule works.

Nobody was unkind. The examples were simply not representative, and the rule that came out of them is wrong in a way that is invisible until it meets something new. That is the whole of it, and a child who has done this understands algorithmic bias better than most adults.

Prediction, which is what a language model does

Play the next word game. Somebody says a sentence and stops, and everyone guesses the next word. "The cat sat on the..."

Then notice two things together. First, you were probably right, because language is predictable. Second, you were guessing from what usually comes next rather than from knowing anything about this particular cat.

That distinction is the single most useful idea a child can hold about these systems.

Instructions, which is programming

Have your child give you exact instructions to make a sandwich, and follow them with deliberate literalness. Put the knife in the jar handle first. Put the bread on top of the plate that is on top of the other bread.

Children find this extremely funny and it teaches precision better than any lesson about syntax.

What is not on the screen

Worth adding for children of eleven and up, because it is left out of almost every explanation. These systems are built by companies, trained on writing that people produced without being asked, run in buildings that use a great deal of electricity and water, and shaped by decisions about what they will and will not say.

None of that requires a technical explanation, and all of it is part of understanding what the thing actually is.

Then, and only then, the screen

Once a child has the sorting, the birds and the next word game, sitting with them at an actual system is genuinely useful. Ask it something you can check. Ask it the same question twice and see whether the answers match. Ask it to do something it refuses, and talk about who decided that.

The aim is not a child who can use these tools, which they will manage without help. It is a child who knows what kind of thing they are looking at.
