grammatical agreement

I'm looking for a couple good exercises that I can use to improve my grammatical agreement skills. Can you please provide a several? The ones I came across were mediocre.

For example, I would have written, "I don't like this kind of movies," when I should have written, "I don't like this kind of movie," or "I don't like these kinds of movies."

The reason I wrote "this kind" and "movies" because I was thinking there are a several movies under one kind--as in a genre.

Many thanks in advance.
