And here are my wonderful powerpoints from Open Class (we did Day 3 of lesson 12). I made them from scratch to be unique.
The House Rooms one we used for Listen and Read A, reviewing rooms we'd already introduced. I found really beautiful mostly monochrome rooms to illustrate the words my co-teacher suggested. Then there's a diagram of a house at the end with all the rooms again (except balcony, since it actually has porches instead).
The Jjanggu sentence game is a white board game but would probably work just having students write the sentences in their notebooks or on paper. The second slide has a photo with the faces cut out, which you can insert your own photos behind. I put pictures of myself and my coteacher there, and the kids thought it was pretty funny. (One girl said, "Teacher...scare.") It also took a long time to play, since I did two sentences per slide. We finished it the next class.
