Lesson details

Key learning points

  1. Rendering can be used to enhance complex shapes.
  2. Annotation using subheadings can be used to analyse products.

Keywords

  • Render - to add details like shading, texture, and depth to a drawing to make it appear more realistic

  • Annotation - a comment added to a diagram or image to provide explanation, clarification, or extra information

  • Tone - the lightness or darkness of an area, which helps create a sense of dimension in the image

  • Texture - how something feels or looks like it would feel if touched

Common misconception

Annotations can replace the need for a clear and accurate sketch.

Annotation provides further explanation or clarification on what is not visible in the sketch.

Annotating live in front of the pupils is a great way to exemplify the process of annotating a sketch. This could be done using a visuliser or on a white board.
