[HUE]

Have you considered reviewing particular themes/grammar. Review sounds boring, so maybe that's not the best word. But you can return and do a theme again, just tweak it a bit. If you talked about vacations, for example, why not talk about dream vacations? Or horrible vacations? Or make students put together a travel plan in groups? Or video skits focused around travel?

The last idea on videos would make a good project, which leads me to another idea: projects. How about getting students to work on something together in groups for two or three weeks?

I hope these ideas help.

Good luck with the after-school classes!
