I am not sure what to say. There are less than 2000 words in the book. There are some pages with less than 5 words on them. Huge illustrations on each page. There is a story. The books are cleverly marketed. I think these books are ideal for Year 3, and for weak Year 4 readers.

The story is so simple it would not be beneficial for Year 5 readers, even the weaker readers, except for the boast of having finished a book.
