• Children to know their multiplication and division facts to 12 x 12 for the Year 4 multiplication check.
• Multiplication is commutative for any number of multiplicands. Division is not commutative
• Children to have a strong grasp of factor pairs.
• When multiplying two positive whole numbers, the answer will always be larger than either of the starting numbers.
• Linking facts to our times tables ie The 4s are double 2s, 8s are double 4s and 5 x is half 10x
• Division can be achieved through grouping and sharing
• When you divide a whole number by another whole number, the answer will always be smaller than the original member
• Children are able to select the correct operation and the most efficient method to answer a question

Multiplying by a power of 10 does not just mean “adding a 0”.

Common Misconception – Data

Using the wrong graph type for the data type – discrete or continuous.
