I was talking to THE Bill VanPatten a lot this week about Second Language Acquisition and the possibility of working on some projects together soon.
In one of our convos, he brought up a way he had done Weekend Chat in the past. Now, the way I typically do weekend chat in levels 1 and 2 (where I normally end up teaching for whatever reason), has varied a little bit and evolved since I was doing more textbook teaching.
In level 2, I would use it to practice the preterit and have each student look through the textbook and write 3 things that they did over the weekend. I would check their conjugations and would ask them to share them with the class in Spanish. Then we would move on to something else after we finished.
