I am in the lovely position of choosing new textbooks for the courses above. I would like to have books that are more than just cover to cover black and white exercises - ideally containing investigative tasks, ICT applications, 'rich' problem solving tasks and maybe even a few pictures for some light relief (of a mathematical nature obviously) The Rayner ones I have seen for IGCSE seem very comprehensive but not very inspiring to look at. I have also seem the Hodder published 'Cambridge Checkpoint' series- are these any good? I would be most grateful if people could suggest good ones they use or warn me off rubbish ones before buy I put my money down. Thanks in advance.
