I'm a PGCE student and am in the middle of planning for my first lessons to be delivered after half term! :s I have planned 30mins in the lesson for the class to draw a rough sketch of themselves from the photo they were asked to bring in as homework using pencil and paper. I have then planned 30 mins for the class to improve their drawing by tracing their image with acetate and marker pens. They will then be using the acetate as an aid when they start painting their portraits next lesson. They have previously been taught about the proportions of the face, and i will provide a short demonstration to drawing portraits to go along with this. Is this plan too ambitious for a Year 9 class? If so what would you suggest to make it more understandable?
