At school, Michael Phelps could not sit still and found it difficult to concentrate. His teachers said he couldn't focus on anything. But then he found his passion for sport. His mother encouraged him and helped him to develop his swimming ability. His reading improved when he read books about sport. And his Maths improved when the problems reflected his interests, for example, 'How long will it take to swim 500 metres if you swim three metres per second?' Through hard work and never missing a day's practice, Michael became an Olympic champion, winning twenty-eight medals, twenty-three of them gold.
