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 9 books are similar in complexity to level 8, with strong patterns and similar events and episodes. Nonfiction titles use nonfiction tools—including signs, labels, captions, and diagrams—where necessary. Single-word spacing is used from level 9 upwards. In addition, very high-frequency words appear consistently without vowel markings. These features will help the students get used to the traditional norms of printed Arabic. As we grow up, our bodies grow and change with us. This information book by Teresa Heapy looks at the changes that happen—from our eyes and teeth to our height and strength. Children can chart the changes our bodies go through from baby to six years old in the timeline on pages 14–15.
