Over the years we've marveled at various home activity walls, but leases can limit options for families. The felt board is a great solution that renters can put up without altering the walls. Just make it huge.
fishing for ideas for preschoolers--great blog of preschool curriculum--grouped by what area they teach (social emotional, sequencing, etc), what kind of activity (board stories, puppets, etc.), themes, and holidays, etc. AWESOME.
