Once children have learnt the 2x, 4x, 5x and 10x tables they can put their knowledge to good use by working out division questions. Because division is the inverse of multiplication the only knowledge needed to work out 14 divided by 2 is that 2 x 7 = 14.
This is a more abstract way of working with division and children should have had a great deal of practical work sharing out coins, cubes, sweets etc before moving onto this type of question.
