Factors, composites and primes - What's the problem?


Many students who know their 'table's experience difficulty with factors, composites and primes. This is because a deep understanding of factors requires a significant shift in thinking from the equal groups or repeated addition idea that underpin the traditional 'times tables' to the 'scalar' idea for multiplication that instead of focusing on the number in each group, the scalar idea shifts the attention to the number of groups or multiplier. Factors, composites and primes are much more than a topic or chapter in a textbook to be considered once or twice a year. They require an extended understanding of multiplication that is not supported by the equal groups, repeated addition view of multiplication or the 'times tables'. An alternate way of developing the multiplication facts that supports the factor idea will be considered.
