Children may also get started with money, time, and measuring, though it is not absolutely necessary to master any of that. The teacher should keep it playful, supply measuring cups, scales, clocks, and coins to have around, and answer questions.
In the simplest cases, the two fractions will already have a common denominator. In this case, add the numerators and then reduce the resulting fraction.
Start by following the basic process for fraction multiplication, turning any mixed fractions into improper ones. Before you cross cancel or multiply, however, swap the numerator and the denominator in the second fraction. This is called taking the reciprocal and it is the key step to turn this into a division operation. Then, cross cancel, multiply across to get the answer fraction, and reduce.
The worksheets on this page have various types of practice for multiplying fractions. Included are problems that focus on cross-cancelling which is a skill that greatly simplifies the process of reducing fractions in the answer step. Cross cancelling prior to multiplying fractions results in much smaller products which are significantly easier to reduce and turn into proper fractions.
