Visualisation of information

Sketches convey information in ways that words cannot.

Students need to learn how to read, interpret and produce visual images — from rough sketches through to formal diagrams. They also need to be able to create visual aids that help them to think mathematically and explain their ideas.

The task Bad Apples is easy to adapt for many year levels. It uses visual imagery to provoke visualisation that leads to algebraic reasoning.
