This story is part of Reading Champion, a series carefully linked to book bands to encourage independent reading skills, developed with Dr Sue Bodman and Glen Franklin of UCL Institute of Education (IOE). This book is aimed at Independent Reading 12, for readers aged 7 years old and up, or in the second half of Year 3. Tommy keeps framing Sam for bad behaviour at school, so the headmaster thinks Sam is a big troublemaker. With a little help from a secretly magic apple, Sam and the headmaster swap bodies! Walking in each other's shoes (literally) they both learn valuable lessons. Reading Champion offers independent reading books for children to practise and reinforce their developing reading skills. Fantastic, original stories are accompanied by engaging artwork and a reading activity. Each book has been carefully graded so that it can be matched to a child's reading ability, encouraging reading for pleasure.
