This is an Oxford Reading Tree series of fiction for pupils aged 7 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 five stages, with each stage introducing more complex narrative forms, including flashbacks and changes in viewpoint; descriptive writing; and extended reading vocabulary. Each stage is supported by a Teacher's Guide, which offers guidance on using Treetops to assess children's reading ability. A variety of activities are included.
