It was a co-op school day, so it was just the boy and me. We walked to Main Street and logged cars by color and make. He didn't seem to like it much, but he's very good at recognizing a car before he sees its badges. He much better liked the bar graph we built to demonstrate the colors of cars we saw, and the pie chart that we made to show which make of car we saw most often. He's a boy of concrete data--just, someone else can collect it.
