I plan on teaching a chess class (5 classes in a sequence, each building off the previous, 1 hour each) to high schoolers, with emphasis on applying chess principles to real life. Now, it'll be unproductive to have players of maybe <1200-1300 strength, since they won't quite understand positional and tactical ideas well, and will likely find the class advanced/unproductive.
Given the short time frame, I'd like to somehow assess their playing strength at the beginning of the first class in as short amount of time as possible, so as to make the rest of the sessions most productive for the rest. Any suggestions?
I thought of tactical puzzles, and someone suggested multiple choice format for guess the move, but both will require a good 10 minutes for the students to have a good chance at getting them right.
