multiplication tables and Division Fact test generator upto mulitply/divide 14

An excel based spreadsheet which works out times table question for you by you putting in part of the sum (e.g. 1; 3; 4) in a random order. You then read this out to children; they remember what multiplication tables they are on individually (Fred could be on x12; while sonja is on x2). You then display sheet on board to peer mark.Division facts sheet works in same way but children have to each division fact test in turn. You type in the answer (e.g 12)..the spreadsheet gives you 144 to read out; the children should know they are on divide by 12s.Hope this makes sense!ENJOY
