I literally have about 55-60 of these drawer units in my classroom! That sounds like a lot (and it IS a lot), but I use them to store all of my literacy and math centers, to store the student take-home book baggies, and as student mailboxes. When people ask me how I keep my classroom so organized, I point out all of my drawer units. I always recommend these to student teachers and co-workers! LOVE them!!
