**Dynamic Representations**

A dynamic representation is a visual representation of a mathematical object that changes in time.

The representations created on Desmos can be set to play (above), or controlled by variable sliders (below).

This site contains static and dynamic representations that are freely available online. They can be used as a teacher modelling tool on a whiteboard or by students on tablets or laptops.

The Desmos representations are best viewed in Desmos. Click on the image of the representation or click "edit in Desmos" on the bottom right of the image. When you open in Desmos you can adapt and save the representations.

When integrated with curriculum and pedagogy, visual representations that change in time can improve students’ conceptual understanding of mathematics.
