What is this experiment about?
A new shape appears in the middle of the screen — your job is to tap the bin it belongs in: circles, squares, triangles, or rectangles.
Questions kids ask
- What's the difference between a square and a rectangle?
- A square is a special rectangle where all four sides are the same length — every square is a rectangle, but not every rectangle is a square.
- Why does shape sorting help with math later?
- Recognizing shapes quickly builds the foundation for geometry, patterns, and even reading graphs and charts.
- Do the shapes always look the same?
- No — size and color change every round, so sorting has to be based on the shape itself, not how big or colorful it is.
