We took this week "off." Well, we left the school books on the shelves anyway.
What did we do instead? Took the hula hoe and rake to the yard, pulled weeds, deep cleaned the house, collected bags of stuff to pass onto a the local thrift store and Boys and Girls Club drive, and more. The oldest four started the work for their religious emblem (scout thing) with their youth pastor, and spent about 2.5 hours working and cleaning at church with him too.
The oldest two were usually found with their noses firmly planted in books when they weren't working, and the younger ones read a fair amount too.
I gave the kids all week to get their rooms seriously whipped into shape. By Friday it didn't appear they had taken it seriously, and I walked in with a broom and trash bags. My method is to brush it all up into a pile in the middle of the room, get the planned furniture rearranging done, then work on that monstrous pile of shtuff. They got to choose what went into the donation bags, but purging wasn't optional. If you have so much stuff it doesn't neatly fit in your storage devices, you have too much stuff. =P~
