What types of change are there

This is based upon the chart found on page 9 of the Edexcel text book for the GCSE 9-1 course from Edexcel/Pearson. I have tried to move the children along the lines of rates of change and the ideas surrounding the problems with data and the need for contextual knowledge to add understanding to the data. This has a direct numeracy link. I have specifically used a literacy focus on the need to add more than one idea to an answer as pupils will tend to focus on just one idea!
