All 100 Times Tables from 0x0 to 9x9 in random order, on an A4 sheet for students to answer, with an exactly matching answer sheet [same number of columns & rows] for teacher to make marking quick and easy. Presentation is clear and easy for students to identify - the question numbers are red [come out grey when printed in black & white] and everything else is grey except the actual questions which are black.
Student sheet has TIME & SCORE boxes to record the time taken to complete the sheet and the scores [marks & percentages out of TOTAL and out of actual questions ATTEMPTED] to record accuracy and speed.
Sheets presented in 2 versions (A & B) where the random order is different in each version so teacher can give students sitting next to each other different sheets so that copying is not a feasible option. Thus, on a particular day, teacher gives out 1A then 1B then 1A and so on.
5 Question [and Answer] Sheets x 2 versions [A & B] presented here. If this is goes OK, there are 100 Sheets x 2 versions [A & B] that could be made available - enough for 1 test per day for every school day of the year!
