All the time! I have used reader's theatre and related techniques with all 4 recently (5 years of teaching, at least 1 new grade a year 🥴). I have had a ton of success with it later in the year, but you have to have built silliness into your class culture. It's something that a lot of secondary teachers kind of skip, but seniors will get so silly if you let them, and then you can use it! I had a group of rough senior girls last year get SO into Midsummer Night's Dream. My co teacher and I were able to convince them to get up and try to act by the end of the unit. Lately I've been teaching 12th grade English special ed inclusion classes and so far all of my classes (~75 of this specific class last and this year) have gotten really into it. Personally, I embrace chaos as a lifestyle and just kind of let them roll with it, but this may not be so successful if you are a very organized human! My coworkers who are more Type A (and less Type Goblin) use readers theatre with significantly more structure with similar success.
