How we scored them

The Shelf Score weighs fit for the reader, contents and edition, value, and the listed reading age or grade level. All five picks list a reading age, marked as from customers, and three also give a 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 children’s books for vocabulary

Start with the reader’s grade

The dictionary suits a grade 1 to 4 reader who looks up words, while the workbook suits practice for grades 3 to 5. For a child who has moved past these picks, browse middle grade books.

Choose a story over a workbook for reading fun

If the goal is words for a child learning English, see best children’s books for learning English. When the aim is reading for pleasure, a story-based title usually fits better than a practice book.

Before you buy

• Check the edition and publication date: the McGraw-Hill workbook is a 2018 second edition.
• Check whether an answer key is included: the McGraw-Hill listing states one is.
• Compare the listed grade level or reading age with the reader’s age, since some listings differ from their own description.

Frequently Asked Questions

Which book suits a young reader first?

It depends on the reader. The DK dictionary lists grade 1 to 4, and the Our Little Library set lists a reading age of Baby to 2 years, marked as from customers.

Does the vocabulary workbook include an answer key?

Yes, the McGraw-Hill listing states that an answer key is included. The listings for the other picks do not mention one.

Does a dictionary build vocabulary?

It can: the listing says its over 35,000 entries come with definitions, usage and examples. It works best for looking up words rather than reading a story.
