Word Roots

Word Roots from The Critical Thinking Co. is a workbook program that teaches Greek and Latin roots, prefixes, and suffixes through exercises, reviews, and games. Students practice breaking words apart, matching meanings, and building new words, which gradually improves vocabulary, spelling, and comprehension across subjects. Designed for upper elementary through high school, the series fits neatly into 10–15 minute sessions a few times a week. Parents appreciate that the books are relatively inexpensive, reusable with younger siblings, and easy to assign without heavy prep. The layout is workbook-traditional, but for systematic word-study practice, Word Roots is a dependable choice.
