How we scored them

The Shelf Score weighs fit for the reader, contents and edition, value, and the listed reading age or level. All five list a reading age or grade level; check whether the age is marked as from customers. 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 fractions workbook

Match the grade band

The listings run from grade 3 to early high school. The IXL book is built for grade 3 at ages 8 to 9, Kumon for grade 6 and up, and Humble Math for ages 10 to 14. Watch for mismatches: the Otillio book recommends grades 4 to 6 but lists a reading age of 13 to 17. For more math practice, see our math workbooks.

Answer key or solutions

The McMullen and Humble Math listings include an answer key, and Otillio includes solutions; the IXL and Kumon listings mention no key, which matters for independent study.

Problem volume

The Otillio book states more than 3,500 problems, McMullen 20 chapters across 250 pages, and Humble Math 100 days of drills. More problems suit long practice stretches; fewer suit targeted review.

Before you buy

• Check the edition year: dates here run from 2008 to 2019.
• Confirm the grade band fits the reader; note ages marked as from customers.
• Check for an answer key or solutions before buying for independent study.
