DIY classroom library crate benches- A neat way to save space in the classroom through efficient use of supplies. It would be a good idea to combine these with bookshelves, but to have the crates serve as the "readers corner." You could label the crates according to students reading level and have the crates be the go-to for "leveled reading" book selection. The rest of the library could be organized by genre.
Crate bench with storage bins for students' journals... Super simple to make and not very costly. Supplies: milk crates (got them for free from Kroger), zip ties, plywood board, foam, fabric and matching storage drawers (from Lowes)
