This pack contains 18 books. There are six copies of each of the Readerful Rise titles at Oxford Reading Level 16. These books are for readers aged 11 to 13 years old. They are for students who are working below expected standard in their reading. The Readerful Rise series ensures that older struggling readers have high-low books with age-appropriate content and topics, that look like the books their peers are enjoying, but are written at a level they can read successfully.
