I am an experienced teacher with the upper grades and this year I was given first grade. I just had my first week of school and have 31 first graders. I am feeling very overwhelmed and need advice on how to get all the students to focus. It seems the strategies I used with the upper grades for classroom management don't seem to be working well, since these students are younger and can't focus for long periods, plus there are soooo many of them. I feel worse than I did my first year of teaching and I just don't know how I will survive the year sanely. Please help with any advice. Thanks.
