Fantastic link to loads of Rich tasks for you courtesy of NRich. For each Key Stage there is a Word document which covers the Framework for each objective and has links to Rich tasks appropriate for delivering that content. There is then also an Excel spreadsheet for each year which lists all of the MPA skills (process) and shows you which Rich task supports delivering that skill. Again, it is hyperlinked to the resources so it is easy to follow. These are at http://nrich.maths.org/public/viewer.php?obj_id=5665
