How we scored them

The Shelf Score weighs fit, contents and edition, value, and any listed reading age or level. Several listings state both, while the visual guide and the limited-data pick state neither. 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 grammar workbook under 18

Match the grade level to the reader

The Evan-Moor pick lists grade 4 and up, reading age 9 to 10 years; Carson Dellosa lists grades 7 to 8, reading age 12 to 13 years. When the title and the listed grade disagree, read the listing. More level-matched choices: our reading and phonics workbooks.

Decide between practice and reference

Evan-Moor and Carson Dellosa teach through exercises; the Jara Kern pick explains rules through 50 infographics. Match the format to how the reader learns. Our homeschool curriculum lists pair either style with lesson plans.

Before you buy

• Match grade level and reading age to the reader; the Rees title names grades 3, 4 and 5 but lists 3 to 4.
• Check for an answer key: the Evan-Moor pick states one, the others do not.
• Note the edition year: from February 5, 2015 to August 4, 2020.
