Hi! I'm Tess, a tile who loves to grow things.
How much ground does a shape cover? That's its area.
Area = how many little square tiles it takes to cover a shape.
Every level goes Learn → How → Explore → Quiz: meet the shape, see a worked example, poke a demo to see why, then try it.
Five worlds, from tile counting all the way to circles, π and polygons.
Tap, click, or drag. Works great on a tablet.
Each world opens its first level. Win a star to unlock the next one.
