Here my 1st graders first drew their picture in pencil & then traced with glue. The following week they used oil pastels to color. I think I like the result of chalk pastels and glue line drawings better....but I don't like the mess of them!!! One of the concepts I was trying to get through to my first graders was ground. We talked about foreground, middle ground, and background, but I was more concerned with getting a ground line in the picture so their aliens weren't floating. As you can tell...most of them got it(you'll always have a few?!?!).
