When we compare lists of factors of two or more numbers, any factors that are the same are the common factors.

The distributive law says that multiplying a number by a group of numbers added together is the same as doing each multiplication separately.

 In this unit pupils will use knowledge of the distributive law to calculate products beyond known times tables facts and relate this to partitioning one of the factors. In the future unit pupils will explain the relationship between multiplying a number by 10 and multiples of 10. 

In the prior unit pupils explained how each part of a multiplication and division equation related to a story. They partitioned one of the factors in a multiplication equation in different ways using representations. In this unit pupils will use knowledge of the distributive law to calculate products beyond known times tables facts and relate this to partitioning one of the factors.
