Common misconception
Pupils who are insecure with their times tables may not be efficient at finding factors and multiples.
Provide children with a multiplication grid to support them in identifying factors and multiples. When finding a multiple, ask: 'Is it in the x times table?' When finding a factor, ask: 'Which times tables is this number in?'
