This is one of my favorite chalk projects. I got the idea from Artsonia, and have had success every year I have taught it. I did this project with 2nd grade and it took 2-3 class periods.
One the first day, we draw the landscape together on black paper. I then tell the kids we are going to draw with glue. They look at me all confused, which I think is funny . I show them how to trace their pencil lines with the glue. I have them practice on scrap paper first.
On the next class period we start the chalking. I demonstrate how to blend colors. We look at the color wheel and I show them how colors near each other blend nicely. The choose either warm or cool for the foreground and the opposite for the background.
I make sure to pass out wet and dry paper towels so the kids can was their fingers before changing colors.
This student was absent on the day we did the glue, so she used chalk first and then outlined with black oil pastel.
