Learning Objectives:
  •  Learn how to create smooth and gradual variations of tone when shading
  •  Understand how different weights of pencil can influence how light/dark and soft/hard pencils can be and how your choice of pencil might influence your shading
  •  Learn how to neaten and refine work as it progresses
What you will need: 
Sketching paper (or your sketchbook), a soft pencil (preferably 2B or 4B), rulereraser, and a pencil sharpener.
Tips for shading effectively:
Your Task (Part 1):
For this exercise you will need to draw two long boxes on your page and shade them from dark to light from one end to the other. In the first one, a stepped gradient takes you 
Extension task:
To the right is an example of both tonal scales completed. 
For a challenge, have a go at creating a stepped gradient with more steps to the video above and a smooth gradient that shows a wider range of tones.
Your Task (Part 2):
Once you have mastered shading linear gradients, have a go at creating a spherical gradient. The video below shows you how.
Further Extension Task:
Practise drawing some of the gradients from the image below. If you would prefer to use the template on the right you can download it, print it and trace it. However, you can draw them by hand if you wish.

Top Tips
  • Keep your pencil sharp and hold it at a shallow angle when shading
  • Layer up your shading gradually, starting with the lightest tones
  • Smudge your shading between layers, but be careful not to smudge out of the area you are working on
  • Don't smudge so much that the shadows and highlights become a similar shade of grey
  • Rest your wrist on a piece of scrap paper to prevent unwanted smudging
