I used a document sized plastic bend with a lid that is easy for the kids to remove and put back into place.
I filled the box with standard homework supplies: scissors, tape, glue sticks, crayons, markers, pencils, notebook paper, pencil sharpener, bookmarks, etc.
This little piece of organization took hardly any time and cost $0! We already had the supplies on hand from our Back to School Party at Ma's. I also found the plastic bend tucked away in a closet. At one point, I used it as sensory buckets when the kids were younger. I love it when things can be recycled!
Here's to an organized 9 months of homework. :)
