Lots of different animals live in the Arctic and the Antarctic. They must work hard to find food, and to look after their babies.

Ladybird Readers is a graded reading series of traditional tales, popular characters, modern stories, and non-fiction, written for young learners of English as a foreign or second language.

Beautifully illustrated and carefully written, the series combines the best of Ladybird content with the structured language progression that will help children develop their reading, writing, speaking, listening and critical thinking skills.

The six levels of Readers and Activity Books follow the CEFR framework and include language activities that provide preparation for the Cambridge English: Young Learners (YLE) exams.

BBC Earth: Ice Worlds, a Level 3 Reader, is A1+ in the CEFR framework and supports YLE Movers exams. The longer text is made up of sentences with up to three clauses, some expression of future meaning, comparisons, contractions and relative clauses.
