The most recent sets of mental arithmetic questions have now been published for years 4, 5 and 6. For year 4 it is very much about multiplication and division, including some of the easier rules of divisibility eg a number is divisible by five if the units are five or zero. The year 5 sets of questions concentrate on knowing times tables as well as being able to use this knowledge to answer further questions. There is one very tricky question here: what is 28 x 3? One way to do this is to double 28, making 56 and then add on another 28 to make 84. The year 6 sets include multiples, square numbers and prime numbers. By the end of year 6 children should know at least the first 10 square numbers (eg 4 x 4 = 16) and be able to recognise small prime numbers.   Go to year 4 mental arithmetic Go to year 5 mental arithmetic Go to year 6 mental arithmetic
