It's dinner time in the prehistoric Rock household, and the kids Dug and Trogla are fed up with eating mammoth all the time.

It's so boring! They devise a plan to get a change of diet, but things quickly start to go wrong.

Cave Kids is a book-banded reading book for more confident readers, carefully levelled at White Book Band for guided reading.

Beautifully illustrated throughout, this 785-word fiction story is suitable for ages 7 - 8.

Cave Kids features a more demanding text with extended vocabulary and literary devices.

It has more clauses in sentences, the use of metaphor is introduced, and the story plot is more involved. Cave Kids is part of Ransom Reading Stars, a structured programme for children learning to read.

The series has fifteen levels: four phonics levels and eleven book band levels (Pink through to Lime).
