A powerpoint to explore the magnitude of numbers both positive and negative.
An insight into algebra too. When I did this in class I explored what would happen with different values of a and x. I used this to explore negative numbers and as a starter to moving on to multiplying negatives

A nice powerpoint looking at the size of positive and negative numbers. Very good to address the common misconception that, for example, -5 is bigger than 2. A useful resource to use as a starter or plenary activity on this topic.
