Well, this week I let my 6 year-old run the show. One afternoon this week, he was wandering around the house looking for something to do. Finally he said, I want to do that weekly project thing we used to do. It was neat to see that he had not forgotten about the Weekly Unplugged Projects.
I was in the middle of something, so I told him the theme was "Long" and he sat for a while and brainstormed some ideas. Finally he hit upon something he thought he could do independently. He got the yard stick and a piece of paper and pen, and then wandered around the house measuring various things. As he measured each thing, he wrote down what it was and how long it was. He wanted to compare them and see what was the "longest."
I usually like to be a bit more involved, to give us something fun to do together, but it was fun to see him do it himself.
