The 25 questions in a test will be selected from the 121 possible questions that make up the 2 to 12 multiplication tables.
The below table shows the minimum and maximum number of questions (items) that will be randomly selected from each multiplication table.
Additionally the second table shows the minimum and maximum number of questions that will be taken from KS1 tables (i.e. 2, 5 and 10 multiplication tables) and those that will be taken from KS2 tables.
There is therefore an emphasis on the more difficult 6, 7, 8, 9 and 12 multiplication tables but KS1 questions are included to ensure an appropriate breadth of coverage. It should also be noted that questions will not appear in the reverse order in the same test, i.e. 3 x 8 and 8 x 3.
It is interesting to note that the first number in a question (n1) denotes the multiplication table the question is part of, for example 3 x 9 is considered part of the 3 multiplication table. The maximum and minimum numbers in tables 1 and 2 will therefore be applied to the first number in the multiplication. However, the secondary number will also be monitored to ensure instances of each number are within +/-1 of the minimum and maximum parameters.
This makes the specification largely commutative, minimising any impact of the order of the numbers in the questions.
