Our family has been a part of co-ops in so many shapes and forms over the years. We’ve gone from 2 to 8 to 25 (at least) families; we’ve done just-for-fun classes, to studying history through the arts, to learning via the classical approach; teachers have ranged from “just” volunteer moms to employed teaching professionals in their fields. We’ve had classes in living rooms, Sunday school rooms, museum halls, and playgrounds. Co-ops can look and be set up in so many ways, and while none of them are perfect, I am sold on the format and the opportunities they provide.
