Some children have trouble with the concept that the line they are following is the edge of the shadow, but once you point this out to them, they do well. Some children also have trouble standing still long enough but they usually will when they see that they will not have a picture if they keep moving. It helps to allow them to experiment with what their shadow can do before you do the drawing activity. If time and interest allow, the children like to color in the outline of their shadow, draw facial features, clothes, etc. Be sure to have each child write his name by his picture.
Children trace a body pattern onto white and black paper and cut out.
Decorate the white body to look like themselves. Glue onto paper and draw outdoor scene. Children glue shadow on the opposite side of the paper as the sun. While the kids are outside playing, let them trace each others shadow with sidewalk chalk. This will give them something different to do and they will enjoy it.
