Teaching grammar terms

How I teach grammar depends on age of my students. Usually I avoid using difficult grammar terms with young learners, with elder students I try explain grammar vie formulas using symbols. Once they learn by heart symbols they can easily use them in their speech.

I usually teach grammar which is on the curriculum. I use textbook but I also use resourses from internet.

I'd agree that simple grammar structures could be enough for colloquial speech. Whereas written and academic speech requires more complex structures to cover more sophisticated meaning. Then, students need to know the terms to manipulate with grammar structures to reveal meaning, idea they want readers to understand.

Thank you for the idea to think about, I go with "Grammar is the business of taking a language to pieces, to see how it works" David Crystal
I teach simply grammar, the main reason is a lack of time, "less is more"my students will know simple grammar, however will speak English, at least they will try to.

Most teachers decide to use some but not all grammar terms in their classes because they could confuse learners. Some teachers use only simple terms, like "Tense", "Perfect" or "Past",  because they don't want to confuse their learners. Which one is you? Do you think that students need to know the basic grammar. terms only?
