So, I've been teaching for five years, and I have a pretty well behaved class. Their worse problem for me is talking. However, no matter what I try, they always misbehave with a sub. For example, today, two girls got into a scratching war when the sub was there. This type of behavior does not happen for me. Any suggestions??? What am I doing wrong that the kids continue to misbehave with a sub? And yes, there are consequences for their actions such as a letter of apology to the sub, silent lunch, phone calls to parents, etc..
