This activity contains a set of differentiated questions worth 20 marks in total, it also includes additional extra challenge tasks for higher ability students to complete. This worksheet could be used as a homework or as an extension or revision activity in class.
I have included a comprehensive mark scheme for teacher or self-assessment of the work, there are also details of grade boundaries which I use to RAG pupils work against their target grades, a full explanation of how I do this is included.
Thanks for looking, if you have any questions please let me know in the comments section and any feedback would be appreciated :)
