Key Trouble

Key Trouble is part of the Oxford Reading Tree, a reading scheme that has taught many young children to read through the adventures of Biff, Chip and Kipper. This edition comes in a refreshed design, with new covers and artwork by Alex Brychta, whose illustrations are meant to draw young readers in and make the stories more enjoyable. The characters and storylines of the scheme remain the same. The only change at Stage 3 is a new story, The Egg Hunt, which takes the place of The Dolphin Pool. The scheme has also been reorganised, with some stages renamed or renumbered to make the progression simpler.

Alongside the books, the scheme includes support for adults. Teachers receive free notes with each pack, along with guided reading cards and a new Teacher's Handbook, and there is a special edition for Scotland. Every Storybook from Stages 1 to 9 has a Take-Home card to help parents and carers read with their child. Downloadable photocopy masters are available on the publisher's free resources website.
