This story is based on the factual behaviour of polar bears in the Arctic region. The three chapters describe how two cubs, at three months, six months and two years, survive the freezing conditions of the North Pole. Silver level titles (equivalent to the White bridging book band) use sentences with two or three clauses and the length of the texts extends to around 1000 words to help build reading stamina. Real-life problems are also introduced to encourage empathy. PM Plus Storybooks feature a classic story structure with tension, climax and resolution to engage young readers. The books have been written using carefully selected vocabulary to ensure children experience reading success. #pm19-offer
