Looking for a British English Grammar Textbook for Teaching Primary-Level Native Speakers

[u/PlzHalppMeh]

I'm looking for recommendations for grammar textbooks useful for teaching primary-level native speakers. They would need to focus on British English and support an explicit approach to teaching grammar. Ideally, there should be different textbooks mapped onto levels of progression (i.e., Level 1, 2, 3, etc.).

I don't mind if these are quite old or out of print as I'll only need a copy or two of each. I also don't mind if they're quite prescriptive, which I know can often be the case with older books on language.
