# Teach the Machine
A machine learns by looking at the
examples we show it.

K-2 · Unit 3 · Student lesson

Teach the Machine

A brand-new machine knows nothing. If we want it to tell a cat from a dog, we show it pictures. The machine looks for what the cat pictures have in common — maybe pointy ears, maybe whiskers.

That is why the examples we pick really matter.

What we’re learning at school

This week your child learned that a machine learns from the examples we show it.

Try this together — no device needed: play “teach a grown-up.” Have your child pick a group — say, red foods — and “teach” you by naming a few examples.
