This project was a great way to introduce my 4th graders to mixing tints and shades to create value. We had been working for several weeks on mixing colors to create a color wheel and a monochromatic painting and now we were ready for tints and shades. First, we drew mirror images of a city and painted one city using tints and the other city using shades. The best part was adding the gold glitter in the night sky when their cities were completed. I find that a little glitter can be a great motivator to finish a project!
