I'm using this binder at school. I love how it slides the ring over, instead of opening downward.
I've got all my classes in this binder, separated by period. I put all my grading in for the weekend, or evening.
And...As I stand here teaching my sixth graders, it makes me smile to think that the Trapper Keeper I used in 6th grade gets a new life in this 6th grade classroom.
