I feel your pain and hear it too!!!
I am having the same problem with my homeroom class (4th grade). I have a "Get in Gear" poster on the wall that lists all of their morning reponsibilities that must be taken care of before they begin working (check STAR book for notes, homework, make lunch choice, sharpen 2 pencils). I spent time at the beginning of the year going over this routine, but still, I have students that do some or not any of it. Also, the noise, converstaion is driving me crazy. I understand the need to talk/socialize when they first enter, but I have been very unsatisfied with how long it takes them to get settled. How many posters feel that students need a few minutes to meet and greet or should they be expected to come in quietly and not converse at all? I have really had problems with how to approach this problem. I did make a copy of the "Get in Gear" poster as individual check sheets for certain students I felt would benefit form this. But I am finding that they check it off without even doing it. I thought of giving them a time limit before silence is expected. If students arrive at 7:55, should they be aloud to converse until 8:00 or 8:05 before they are expected to be quiet? I just don't know. I do have a behavior book taht I record infractions in. If they get a mark in the book, then they do not receive a sticker at the end of class. I do not have any whole class reward system though and wonder if thath would help. Sometimes I just get sick of having to bribe students into following classroom rules and routines. This particular class is driving me up the wall with the noise. They are unable to remain quiet for very long and when talking in group activities, they have difficulty using quiet voices with one another.
Sorry that I do not have any advice. I do not mean to take away from your vent by adding my own and asking for help, but I too am in the same boat. Posters, help us please!
