How we scored them

The Shelf Score weighs fit, contents and edition, value, and the listed reading age or level. Four of the five picks list a reading age or grade level.

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 kids thesaurus for school

Match the reading age to the student

Check the reading age and grade level together; the two do not always agree. The Scholastic listing pairs reading age 6 to 9 years, marked as from customers, with grade level 4 to 7; the American Heritage listing is clear at grades 7 to 10. For more school-year reading, see books about starting school.

Count what is inside

The Scholastic listing names 500 headwords and 2,500 synonyms; the DK volume names more than four thousand entries; the American Heritage listing names 6,000 entries and 70,000 synonyms. The 2020 Merriam-Webster volume adds parkour and dystopia. Browse picture books about school for younger readers.

Before you buy

• Check the edition year: the Scholastic listing is the 2006 revised edition; the Merriam-Webster Dictionary and Thesaurus is the 2020 newest edition.
• Compare reading age with grade level: two listings pair 6 to 9 years with grades 4 to 7.
• Confirm the format: the Collegiate listing is hardcover; the Dictionary and Thesaurus is trade paperback.
