Okay, B., this post is for you since you asked :).
I am a firm believer in natural consequences for my children. But you know, sometimes there just isn't one that corresponds directly with their behavior. Overall our dc are obedient, helpful, respectful, loving, playful, and cheerful; but there are times... For those times I have a very loose behavior chart. Mainly, for the olders, I use it for disrespect or not following through with something I've asked them to do (several times). I am not 100% consistent, but the tool is there if I feel it necessary - I guess you could say that I use it intermittently which, from a behavioralist point of view (which I'm really not), is suppose to be the most effective. Montessori purists are perhaps aghast that I would even discuss this! It goes against their natural learning and is imposing, right? I agree. On the other hand, it helps remove me and the child out of a situation which can sometimes be a good thing. So here it is:
There is a simple grid with their name at the top. One of those round magnets is in the block. Each time it is moved down. When it reaches the bottom they loose a priviledge and start all over again. Usually they lose whatever the next fun thing is and a lot of the time it ends up being not watching a TV show or something like that. It just depends on what's going on in life and it's always my perogotive. Yesterday both the olders reached the bottom and coincidentally lost a priviledge at the same time. They lost the treat of having ice cream on the way home today while the youngest (who did NOT loose a priviledge) got one. As we approached the house middle dd said, "Mommy, I'm glad you don't spoil us," so I guess it's not too bad. It may be a week or even a month between priviledge losses but it does help to have that option for us. It removes me, the child, and emotion out of the consequence and moving the magnet will oftentimes help the child check herself and calm down (or focus on responsibilities).
Younger dd's is a little different. She just has a smiley side and a frowny side (are those real words?) with 3 magnets in the smiley column. If she moves all 3 in one day she looses a priviledge. I can't even remember the last time she lost a priviledge.
I hope this works. I uploaded a pdf file to googledocs so you can just print it. Here is the link:
Let me know if this works!
So there are my very un-Montessori, un-natural consequences, negative consequence charts! Fortunately, life is full of natural consequences so it's used sparingly.
