Are your children loners or groupies? The setting can make all the difference. Some kids need to absorb the energy of a group and need to bounce their ideas off others in order to learn. Unless you live in Timbuktu, co-ops, library groups, scouts, church groups, and other opportunities abound. The more your little groupies are involved, the better.
Other kids are too distracted in a group setting and prefer to process information on their own (or with just you). They prefer to compare their new experiences with their own prior knowledge and perceptions. While a few social gatherings are a good thing for your loners, don’t expect them to be enthusiastic with a different co-op meeting every day.
