How it works

Link each body part to its job: the heart pumps blood, the lungs take in air, the bones hold you up.

Questions grown-ups ask

How long is a lesson?

Most lessons take 5 to 10 minutes: a short learn card, practice that is marked as you go, and often a quick game. Little and often works best.

Do children need an account?

A grown-up signs up and adds a child profile; children never need an email or password. Class students sign in with their class code and PIN.

Is the practice the same every time?

No. Every practice step is generated fresh, so a child can repeat a lesson as often as they like and still get new questions.

Can I see how my child is doing?

Yes. The parent dashboard shows each programme, the level, stars, when your child last practised, and the skills that are going well or need more work.

Can I print the lessons?

Lessons are made for the screen, but every practice sheet can also be printed from the worksheet maker.
