extend / expand /build on
In class , how can I express the following naturally?

These are just a few words / expressions. The list can be expanded/ extended if you look up your dictionaries.

These are not the only expressions we have there are many more you can build on

You can build on these and create a wider list of words

Could you say how a teacher would express this'?

Answer

Expressions usually aren't in dictionaries, as they usually are not individual words.

I would say:

Here are a few expressions you might see or encounter. These are not the only expressions and you can build a wider list and can provide your own examples.

Example in Spanish an expression might be: Mi casa es su casa. The English equivalent would be: Make yourself at home.
