It starts in preschool and grows exponentially with each passing year: that barrage of permission slips, report cards, and other paperwork that somehow has to find its way from your child's backpack to you and back to school again. One solution is a family in/out box system that serves as a visual reminder to kids when they're loading or unloading their backpacks.
Mount the transparent office-paper sorter at eye level, just above your child's backpack hook.
Label one slot for each child and another for parents.
Each day after school, kids hang up their backpacks, remove important papers, and place them in your slot; you read them, sign them if necessary, and place them back into your child's slot. The child then returns them to the backpack the next morning.
