Containing one of each of the six titles at stages ten and 11, pack B, this collection is part of the "Treetops" series of fiction with built-in progression for pupils aged seven to 11.

Specially written for children who need the support of carefully monitored language levels, the stories are accessible, motivating, and humorous.

The series is organized into "Oxford Reading Tree" stages (from stage ten to stage 14), with each stage introducing more complex narrative forms, including flashbacks and changes in viewpoint; descriptive writing; extended reading vocabulary; and more pages, more text, and fewer illustrations.

Each stage is supported by the teacher's guide, which offers guidance on using "Treetops" to assess children's reading ability, and includes a variety of activities (comprehension, writing for a range of audiences and in different forms, discussion and role play) many on photocopiable sheets.
