This is one of my favorite winter art projects. I have put it out every year in January. Below you can see how I've set it up on the art shelf. To do this work, the child takes one blue paper (construction paper cut in half) and one white paper (2 inch by 9 inch strip of white construction paper) and places them on the tray. Then they carry the whole tray to their table.
I didn't take any photos of the process, so I'll try to explain it. The first step is to tear the white strip of paper in half lengthwise. One torn piece is then glued to the bottom of the blue paper to represent the "snowy" ground. Then the child uses the crayons to draw a "wintry scene". The final step (if they wish) is to tear small pieces of the remaining white paper. These little pieces are then glued onto the picture to become the falling snowflakes. The two examples shown below were completed by children in my class this week. The top photo shows the "torn" snow and the bottom shows how one child drew their own snowflakes with a white crayon. I love how sweet and unique each of these creations is.
