My class doesn't want to do anything. They're so low level wise. I gave them an assignment today to write definitions of some spelling words and after an HOUR, they were still on #2, #3. I know that part of that problem is that these 4th graders really don't know how to use a dictionary. Morning work, which should take 15-20 minutes, also takes them an hour. Their behavior is horrible. I have individual behavior system and a group one and neither phase them. The don't know how to work quietly. They don't know how to work together. They're flat out MEAN to one another. So much so that I had the assistant principal come talk to them and he was brutally honest with them. They just don't get it. We can NEVER get through what we need to in a day. I'm supposed to teach reading for an hour a day and same with math. I barely can get to math because once I start they don't understand the things they should've learned in 3rd grade or sooner so I can't move on to the material we need to cover. I think part of the problem is that I have 26 kids and at least half of them have behavior issues. I just don't know what to do. I'm so frustrated!
