NRICH - Square It

Squares
Key Stages: 1, 2, 3 and 4 ★

Two players in turn choose dots on the grid. The first to make a square wins! You can either play against a friend or against the computer.

This game offers an excellent opportunity to practise visualising squares and angles on grids and also encourages students to look at strategies using systematic approaches. Describing strategies to others is always a good way to focus and clarify mathematical thought. Working with tilted squares provides an opportunity to examine the properties of gradients of parallel and perpendicular lines.
