This is a lesson for year 7 who are learning to shade and to create a 3D form. This is the start of a Scheme of work (Powerpoint one) where students draw a pebble and then eventually make a tile in the shape of their pebble and design a relief surface based on Hundertwasser. There are three powerpoints on Tes in a bundle linked to this unit of work or you can use it as a drawing exercise to learn to shade 3D forms. This is a short example showing different steps to get a 3D sphere form and using tonal values to develop this form. There are exercises on markmaking and how to create a tonal value. There are the main breakdown of what is needed in a sphere in tones: Light, light grey, middle grey, dark grey and black with reflected light. There are examples of showing how to shade in the direction of the form. Learning Objective was: To create a presentation on an A3 sheet of your observation drawing studies showing volume drawing of pebble To learn to draw 3D geometric shapes and firstly practise mark making and a range of tones in media: charcoal. To develop observational drawing techniques. This follows with Powerpoint Two and Three where students then begin to : Present preparatory work on a page and to plan a design for clay tile. Develop painting style like Hundertwasser (study the style of this artist) and use watercolours and understand what is a style in Art. To complete a clay tile and paint design on tile.
