I don't have time at the moment to look up the actual links, but just google any of these sites/blogs:
the crafty crow
the long thread
ohdeedoh (search for activities)
skip to my lou
chasing cheerios
5 orange potatoes (nature crafts/activities)
rhythm of the home newsletter/blog (not sure what section)
childhood magic
blue yonder ranch (I think?)...look for "book of days"...I think there's one for each season or month
Like PP, I've gotten lots of great ideas by searching the forums on MDC! Also, on the sites mentioned above, check their blogroll for even more websites with kid's activities.
