Putting vocabulary into flashcards is (relatively) a no-brainer: word -> translation, translation -> word. (Yes, it can be more complicated than that, but that's the gist of it.)
Grammar rules, on the other hand, are a whole different monster: for example, if I wanted to put a grammar rule into a flashcard, I could
- Just list the rule on one side (... and that's it?)
- List a correct example and incorrect example of the usage of the grammar rule on the front, and the correct option on the back
- Not put grammar rules into flashcards at all, just hope I pick them up through using the language
However, none of these options seem very elegant or usable as flashcards. What are some other options for putting grammar rules into flashcards?
