Begin by discussing different facial features and body parts. Have the children point out their own individual features.
Explain that for this activity they will be creating a collage portrait of their face (and/or body) using just basic shapes in different colors and sizes.
Distribute to each child the canvas to create their portrait and provide them easy access to the prepared shapes that have been cut.
Using the glue, have the children be creative in the way they create their portraits. The adult should refrain from suggesting which shapes the children should use (e.g., “Why don’t you use an oval for the head.”) to allow for open creativity.
