Square and Circle Inquiry

This resource from Inquiry Maths states "a square fits into a circle better than a circle fits into a square" leading to a rich task exploring areas, ratios and percentages.

A square fits better in a circle than a circle fits in a square describes the prompt and suggests a variety of ways in which it could be used in the classroom.

Lesson notes provides notes explaining how the inquiry can be generalised, extended and how conjectures can be proved. The notes cover the case of a circle and a square and the case of a circle and a hexagon.
