The 500 Words competition, created by Chris Evans and now hosted by Zoe Ball on the Radio 2 Breakfast Show, is one of the most successful story-writing competitions for kids in the world. It helps to get children excited about reading and writing - this year there were 113,000 brilliant entries.
The 500 Words judges for this year were Charlie Higson, Francesca Simon, Frank Cottrell Boyce, Malorie Blackman and Honorary Judge, Her Royal Highness The Duchess of Cornwall.
The winning stories were announced on Friday 14 June at a live final at Windsor Castle. You can watch the stories being read aloud by celebrities on the BBC website.
You can read all of the shortlisted stories for this year on the BBC website. There were two different age categories, each containing 28 stories. These tales make great bedtime stories - fun for all the family!
How we chose the winners
All of the stories were first read by teachers and librarians. Then our team at The Reading Agency read more than 5,000 of the top entries and helped the BBC decide which went through to the final.
Every year we are amazed by the imagination and creativity of the stories we read. Although in the stories this year we saw lots of discussion about serious topics, such as the environment, politics and human rights, there were also such funny, silly, scary and surprising stories in the mix.
The winning stories this year included the secret life of pants, a trip to the dentist for a T-Rex, and a hilarious re-imagining of the classic joke 'why did the chicken cross the road?'.
There was also a modern fairytale mash-up for the Instagram generation, a heart-warming story about taking care of your friends, and a heart-stopping story of a terrifying walk in the park...
The winning stories were performed at Windsor Castle by Konnie Huq, Sandi Toksvig, Hugh Bonneville, Michael Sheen, Helen McCrory and David Walliams.
