Collins Arabic Big Cat is a guided reading series for ages 3 to 11. The series is structured with reference to the learning progression of Arabic at nursery and primary schools researched especially for Collins. This carefully graded approach allows children to build up their reading knowledge of Arabic step by step. Level 11 books provide more literary language, more complex sentence structures and less support from illustrations. Characters are more varied, with action sustained over several pages. Non-fiction titles include glossaries where necessary. Sentences are still short for better understanding. However, grammatical vowel endings are more evident to encourage fluent reading and to provide familiarity with some higher-level features of written Arabic. Tamima the crocodile is known for always being happy and having a big smile, but one day she gets toothache and can't smile anymore. Can she overcome her fear of the dentist and regain her smile?
