The Critical Thinking Co. Word Roots Level 4 Workbook, Grades 7-12

This book teaches students the meaning and spelling of roots, prefixes, and suffixes that are the elements used to form words in English. Learning these word elements dramatically improves spelling and the ability to decode unfamiliar words. The activities focus on using these words in context to help students incorporate each word into their vocabulary and retain the correct spelling. There are periodic reviews to make sure students retain what is taught in the lessons. Word Roots will add hundreds of words to your students' vocabulary and greater depth to their thinking and writing.
