DIY Lego table using Ikea Trofast storage system. On the top get a piece of wood or something for students to write on and then turn over to use Lego table. Then in the bottom put Legos in one, paper in other, crayons, etc.
Garage ball bin - love this design with hooks for helmets and small bins for smaller balls. Use bungee cords in the middle so you can take out balls at the bottom without digging! Plus lots of other garage storage ideas.
