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 10 books include characters that express emotions and stories with more events. Non-fiction titles introduce terms that might be new to many children. Level 10 books continue to use single spacing and more high-frequency words appear without vowel markings to help the students get used to the traditional norms of printed Arabic. Once, there were 100,000 tigers in the world, but now these beautiful creatures are under threat of extinction. Find out the reasons for the decrease in tiger numbers, and what we can do to change it. Children can re-cap the reasons why tigers are in danger on pages 14-15.
