I teach 45 students for 90 minutes and it's a conversation based lesson.

I do a lot of pair work. I make the activities very simple, as I have mixed levels. However, I create a lot of room for expansion on dialogues and role-plays. So, more advanced or more adventurous students can do more with an activity should they choose.

I also have random pairs present in front of the class after they practice. That puts a bit of pressure on them to practice.

With larger classes, it's always important to simplify activities as best you can. Once the students are working and getting on with the activity, then you can add to it.
