Here is a nice little set of multiplication and division worksheets. For each question there are two coloured arrows; one a multiplication (red) and one a division (yellow). One number has been put into the sequence and all the other numbers have to be worked out following the arrows. This is both good tables practice, good division practice and good at showing that division is the inverse of multiplication. Where the given number is not the first number then the earlier numbers can be worked out by doing the reverse of the arrow instruction. For example if the number given is 24 and the arrow to the left says x6, then to work out the missing number on the left divide 24 by 6, which is 4.
