Part one of a truly outstanding suite of three resources commissioned by the NGfL-Cymru (and developed by eChalk) to help with the teaching of enlargements. This resource helps you introduce the basic concepts of enlargement and scale factors. Why not visit NGfL Cymru's virtual teaching centre...it's a great resource.

The main application in NGfL-Cymru's enlargement suite. Explore enlargements by manipulating an object shape and a centre-of-enlargement. You have full control over how the construction appears (choose positive, negative or fractional scale factors; turn the construction lines on or off; hide or reveal the enlargement; zoom in or out; snap to grid; select a positive quadrant or four quadrant background; manipulate your shape by dragging the vertices).

A lovely whole class resource which is ideal for use with the interactive whiteboard. Pupils are shown a shape which they must redraw at a given scale factor. They construct their shape using a flexible polygon which can then be compared to the correct enlargement.

This state-of-the-art resource for teaching reflections includes worksheets. User-friendly controls make it easy for you (or your pupils) to draw the line of reflection and modify the position and shape of the object. This program is also useful for looking at the equation of a straight line.

Another killer application developed by eChalk for the NGfL Cymru. This program makes the teaching of rotations a doddle.
