I have talked a little about what you can do to be successful in Maths.
Larry Ferlazzo has written a very positive and motivating article entitled Now I know my brain is growing when I read every night. Its about getting students to realise that they are not just born with innate intelligence. That in fact the brain is like a muscle and that it must be exercised to grow.
I also love the visual analogy used in Ms Mercers blog Which do you think your brain and intelligence is? Grass or Glass.
