I've been subbing elementary for awhile and I feel comfortable there. I know the tricks, I can get plans done, everyone does their work. Now I'm working a MS/HS and it is a lot different. I'm just emulating subs from when I was in HS, who were pretty laid back as long as we got some work done. I feel guilty, but really, I have no authority and they know it. I don't want to be the crazy lady who gets all upset. But, as a certified teacher, I'm kind of embarrassed about it. I know that I ought to be doing a better job of management, but if the work gets done, does it matter? I feel like at the elementary level I need to be a teacher, whereas at the HS level I'm just making sure they are supervised. Is that normal? I don't have the repertoire of "tricks" for this age group. Are there any?
