I have decided that if you add the word "party" to anything it sounds a lot more fun to kids. For example..."Come on kids we're going to have a clothes folding party", or "let's go have a math party" or my personal favorite "woo-hoo kids, we get to have a clean up the playroom party". I admit that the older ones are on to me but still play along so we can all have fun. Our kids understand that we are all in this together and we must each play a part.
It's just a lot more fun to have a "party" as we go along.
