Multiplication and division are two key elements of Maths which form an integral part of the subject in KS2. In Year Three children are encouraged to learn their times tables as this will help when multiplying or dividing numbers. Children will be taught other strategies to use as well, for example, simplifying problems to make them easier. They will also be expected to know some of the words associated with multiplication and division such as double or share.

Multiplication and division are easier if you know your times tables. You can practise them by playing our KS2 Times Tables Quizzes. However you still need other strategies to multiply numbers and to divide them. Some problems can be made simpler, for example to multiply 7 by 9 just multiply it by 10 and take 7 away. That makes it much easier to work out.

Take this quiz to find out how good your strategies are when multiplying or dividing numbers.
