Happy April Fool's Day! Are you having fun yet? My kids have already been knocking themselves out trying to fool each other, and me.

I've always viewed the day with a bit of trepidation. As a kid, I remember being on the end of some not-so-funny-to-me jokes. As an adult, I worry about my kids either having their feelings hurt or hurting someone else's.

So here are some good clean fun ways you can get into the spirit of the day:

--Here's a teacher's lesson plan on the day's history.

--Here's a list of children's books about April Fool's Day.

--Find some silly kids' knock-knock jokes, and after-school crafts.

--You might have fun looking at these April Fool's food photos on the left from Dot D on Flickr with the family, and guessing what they really are. (You'll need to go to the Flickr site to find out.)
