How we scored them

The Shelf Score weighs fit for the reader, contents and edition, value, and the listed reading age or level. All four picks give a reading age, marked by Amazon as from customers, and a grade level. None states a preschool age range, so fit measures how close each listing comes to the early end of chapter books. How we pick explains the weights.

Scores run from 9.2 to 9.8: each book’s point total is placed on that range, so more points always means a higher score. Reading age or level counts on a list where at least one listing gives one, and a book whose listing gives none then scores zero on it. Where no listing gives one, the score is taken over the other 85 points. Books carry no warranty, so warranty is not scored.

How to choose the best chapter books for preschoolers

Start at the lowest listed level

A child who is just leaving picture books does best with the lowest listed band. Mercy Watson to the Rescue lists grade level Kindergarten to 3 and a reading age of 4 to 8, the lowest in this set. If the child is not ready for chapters yet, see our best books for preschoolers list.

Check whether the series starts at Book 1

Mercy Watson and Narwhal are numbered series, so Book 1 is the natural first title. Magic Tree House Books 5 to 8 is a boxed set that begins at Book 5, so a new reader joins mid-series. For a kindergarten-age child, see our best chapter books for kindergarten list.

Before you buy

• Check the edition on the listing: Magic Tree House is a boxed set, and the Princess listing does not state an edition.
• Confirm the series position, since Magic Tree House starts at Book 5 and the other picks start at Book 1.
• Compare the listed grade level with the child’s own reading, because each reading age is marked as from customers.
