# A Resource to Support Work on Transformations

##### Stage: 4 Challenge Level:

This page contains interactive games and ideas for developing confidence with transformations. There are a number of non-iteractive resources involving transforamtions on the site such as Mirror, Mirror... and the related activities described in that problem's accompanying text.

### Notes on a triangle

This short film offers opportunities to discuss transforimations and their effects. Why not select a section of the film to analyse and recreate.

### Transformation game

This card-based game offers opportunities to develop confidence in the results of different transformations.

### Penta Play

These games based on the twelve pentominoes were invented by Solomon W. Golombwho came up with the idea of polyominoes.

### Square tangram

Practice at transforming shapes and making connections between the ratio of sides of similar shapes (squares) and areas is a useful short cut to solving the later stages of this problem .

### Bow Tie

Show how this pentagonal tile can be used to tile the plane and describe the transformations which map this pentagon to its images in the tiling.

### Tablecloth

This problem links symmetry and transformations with a generalisation related to the pattern of numbers of colours. An interesting mathematical connection.

### Matter of Scale

This problem examines a proof of Pythagoras Theorem using enlargements and scale factors.
