# Investigating transformations with Desmos

I can investigate transformations using dynamic software

## Lesson details

### Key learning points

1. Dynamic software is a tool that can be used to explore transformations.
2. There are many benefits to using this tool.
3. Different transformations can be carried out quickly.

### Common misconception

Pupils may struggle with only being able to rotate anticlockwise on Desmos.

Turning clockwise x degrees is equivalent to turning anticlockwise (360 - x) degrees.

### Keywords

• Object - The object is the starting figure, before a transformation has been applied.

• Image - The image is the resulting figure, after a transformation has been applied.

• Vector - A vector can be used to describe a translation.

• Polygon - A polygon is a flat (2D), closed figure made up of straight line segments.

Pupils will need access to a web browser during the tasks and paper to record their responses to the questions. Print the tasks or leave them displayed on the screen while pupils work individually on their devices.
