About a year ago if found this discipline chart. We use this in our house and have found it to be very effective. It’s cool because you can let the chart be the bad guy. “Well you did such and such so the chart says that this is your punishment.” Of course you would have discussed everything on the chart ahead of time.
I also love the Laundry room idea. Everything that goes into the laundry room is dirty and then is cleaned and comes out clean. That includes your attitude. Head on over to Confessions of a Homeschooler to download the chart and laundry room sign.
