This programme introduces the four common geometric transformations in interesting settings and in a way that is relevant to students. Translation, reflection, rotation and dilation are investigated as they are applied to common geometric shapes in the coordinate plane. Demonstrations are clearly executed with the main features of the transformations being illustrated and summarised at the end of each section of the programme. The patterns between original and image coordinates for each transformation are clearly illustrated using graphic techniques and tables of values. These generalisations lead to algebraic statements in the form of transformation equations. Students are encouraged to relate these ideas to their own experience and to apply them to create a geometric design or logo. The use of accurate mathematical language is used throughout the programme and illustrations come from urban streetscapes.
