I use a modified version of this hack with fourth graders: Each group has a three - drawer rolling storage cart. (edutopia.org)

Buy «Storage Shelves On Casters» products like Oceanstar 3 - Tier Storage Cart in Espresso, Oceanstar 3 - Tier Shelving All - Purpose Utility Cart in Chrome, Honey - Can - Do 6 - Tier Urban Shelving Unit in Chrome (bedbathandbeyond.com)
