I think they cloned my students from last year and sent them to you! I taught 6th and 8th grade at a low income middle school back then. I found that bribing them with candy was the only thing that had any effect. Isn’t that sad? Of course it was my last resort. I hated doing it, and it cost me a small fortune every week, but it was almost worth it. You have my sympathy - I know exactly what you’re going through!
Yes, candy. They like stickers, too.
