I love all of these ideas for a classroom. There are bracelets to keep track of groups, paint stirrers to separate books and just basically anything to help out in the classroom. As a plus, these hacks aren't even that expensive to make happen.
Keep track of classroom jobs this year with this cheerful Polka Dot Brights Classroom Jobs Clip Chart package. This set is designed to be a classroom job clip chart. To keep track of classroom jobs, simply hang up the chart in your classroom and use clothespins to assign jobs to various students. Simply switch the clothespins around from week to week. There are editable options provided within this PDF package for you to "name" your own classroom jobs
