Which Shape Doesn't Belong?

Any child who is currently 5-, 6-, 7-, or 8-years-old and is a native English speaker.

In this study, your child will see groups of shapes and will be asked which one shape from each group doesn’t belong with the rest. All the shapes in each group will be different from each other, and so we are interested in which shape your child think stands out as the most different.

From early on and well before they learn shape names, children can easily tell different shapes apart. This ability is important not only for recognizing objects in daily life, but also as a foundation for formal math learning in school. In this study, we are interested in children’s intuitive sensitivity to the geometry that differentiates among simple shapes so that we may better understand children’s readiness for learning geometry in school.
