Hands-on maths, from first steps to deep ideas
How a lesson works
Every toy has a 4 to 6 minute guided lesson. Nobody lectures you: you predict, you try it with your own hands, and the maths reveals itself.
Guess first. Each lesson asks what you think will happen before it shows you.
“Your turn” tasks you do with your own hands. The toy notices and ticks them off.
Every lesson builds to a big surprise, then recaps it in plain words.
The same idea turns up in other toys. Follow the links and the maths joins up.
No maths background needed. Tap any underlined word in a lesson for its meaning.
The learning map
Lines are tracks and stops are toys, easiest on the left. Dashed arcs show where the same idea turns up in two places.

Learning tracks
Each track is in learning order, but every toy stands on its own.
