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 4 books are for children who are ready to start to read stories with simple single words or non-verbal sentences with 2 or 3 short words, and with total support through illustrations and extensive use of repetition. Double spacing is used between words to ensure children see where each new word in a sentence begins and ends, with the focus on reading core words. This photographic information book by Moira Butterfield shows the variety of creatures that hatch from eggs, including fish, turtles, crocodiles, seagulls and eagles. A simple pictorial summary with labels on pages 14–15 provides an opportunity to recap and discuss the information in the book.
