G1.1

The Shape Museum Detective

Some shapes are wearing the wrong name — count each one's corners (or flat faces for a solid) and fix every plaque so every name matches its shape.

🎯 Every plaque names its shape by its count. Count them all, fix the wrong ones, then Check.

A shape's name comes only from a count you can see — how many corners a flat shape has, or how many flat faces a solid has. Big or small, tilted or spinning, red or blue: same count means same name. Turn on Fair test to make every shape the same size and colour, so only the count can tell them apart.
