We have had several different chore / reward systems in place over the past couple of years. It seems like we just cannot really find something that works well for us. It is aggravating. I have some new charts with little cards on hooks that I like a lot, but they just don't want to stay hanging on the wall!
I found a site where I can download a chore chart for free! They come in different design styles too. There is a "rock n roll" template that I think E would really like. There are several to choose from. There is also a way to track chores online and an allowance system. I am going to read more about it and send the link to Jenn.
