Frequent (verb) and Frequent (adjective)

Hi,

Does anyone have any good ideas as to how I could check the students' understanding of the differences between these two forms? I am struggling to think of any concept checking questions for this purpose..

Many thanks in advance.

Hi!
I'm not a teacher.
(I hope I understood your problem correctly).
If the students are not familiar with adjective/verb functions in a sentece, the whole thing may be difficult.
First, I'd ask them to identify what part of speech the underlined words are:

Foreign students often frequent Henry's bar.
Foreign students are frequent visitors to Henry's bar.

After they have fulfilled the task successfully, I would ask them to arrange the words in logical order and reconstruct the sentences, for instance

at / run/ frequent / trains / intervals
summer /frequented/ tourists / Hard Rock Cafe / last

And finally I'd ask them to come up with their own example sentences.

Thank you very much for taking the time to offer your suggestion - that's very useful, thanks. As a trainee teacher, these concept checking questions are quite tricky for me at times and it is a skill that I really need to develop.
