I am learning Spanish and I like to watch movies in Spanish with Spanish subtitles. Part of it goes too fast to always notice the grammar, however, often after I have had a bit of a grammar lesson then I start noticing the usage of the grammar in the subtitles.
For me though, having a conversation with a native speaking tutor who corrects my grammar as we talk about something I find interesting is the most fun way to learn grammar. With another person, things that would bore me when I am by myself become interesting when discussed with someone with a different perspective. I am not particularly into cars, but after a a tutor from a less economically developed country asked about how shopping online works in the U.S., I took one of my tutors on a pretend online shopping trip for a car in the U.S. I had great fun showing him the online advertising of the selections of cars near me while he taught me both grammar and vocabulary related to all the options and features of the cars.
Idea!! Listen to media such as watching TV, or movies, or podcasts. practice repeating some of the phrases.
If you are bored find something more interesting to watch.
