For years now I've been producing datafiles and word processing exercises for me (mostly) to use with my Y5 class. They fit in with the topics that I "do" during the year - rivers, ancient Greece, ancient Egypt etc. (the usual KS 2 topics). I've zipped them up into little "packages" and you can download any of interest at my school's website.
All can be edited to suit the age range/ability of your pupils. They are WORD files and JUNIOR PINPOINT files mostly. Find them on the "Downloads for Teachers" page in the "Teachers Cupboard". I don't claim that they are particularly brilliant but they work for me. Take a look - see what you think.
