Okay, that's not really a real word but it is what I have chosen to call this value project recently completed by fourth grade students. I was given a large quantity of white model magic that had been around for a few years. It was beginning to become a little stiff so needed to be used. I decided to turn this into a lesson on value, primarily tints. With a little blue model magic and a larger piece of white model magic, students started by dividing their clay into 5 approximately equal pieces. This would help them as they began mixing so they would be able to budget clay use. The first ball was a small blue one, then white and blue were mixed together to make an only slightly lighter ball of clay. Each ball of clay became progressively larger and lighter ending with a large white ball of clay that became the head of a Caterpillar. Thus, the name, Valupillar. Not only were the students totally engaged in the color lightening process to create the tints of blue, I also had comments that this as the best project ever!
