## Commutativity and fraction problems

In this short blog we will look at how, by using the commutative property of multiplication it is possible to solve complex looking fraction multiplication problems mentally. Previously we looked at concrete approaches to conceptualising the process of multiplication of…

## Fraction multiplication – Making sense of multiplying improper fractions.

In the last blog we looked at why multiplication of proper fractions can be fluently completed by multiplying numerators then doing the same with denominators. At this stage learners will have begun to understand this procedure and the truth of it…

## Fraction multiplication – a concrete approach

Why is the following statement true? For those of us in the know we might be tempted to say on the left hand side if we multiply numerators by each other and do likewise with denominators we will…
