How we scored them

The Shelf Score weighs fit, contents and edition, value, and the listed reading age or level. None of the five picks lists a reading age or grade level. 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 fun fact book for teenager

Match the length to the reader

A teen who stalls halfway through long books may do better with the daily fact book, while a confident browser may enjoy the longer illustrated collection. For younger readers, see best fact books for 11 year olds.

Series or standalone

The daily fact book is the first book of its series, so a reader who likes it will want the later volumes. The other picks state no series position. For more choices by age, see best fact books for 9 year olds.

Before you buy

• Check the edition and publication date.
• For a series, confirm the first book.
• Compare stated topics with the reader’s interests.
