If students cannot follow, the teacher should illustrate the point with suitable examples.

Concrete, familiar examples connect the abstract idea to what students already know.

Asking them to read more at home shifts the burden without resolving classroom confusion.

Moving from the concrete to the abstract is a well-known maxim of effective teaching.
