Hi everyone. I'm a brand new High School substitute, and I'm trying to come up with emergency lesson plans/activities. Please share your fantastic ideas!! What do YOU do when the teacher hasn't left anything planned? Does it matter what the subject is? Also, can anyone recommend good DVD's to show in class? I'm looking for videos that can be effectively shown for only about 20-30minutes. That way, at least 10-15 minutes can be reserved for class discussion. Thoughts? Thanks!!
