Students learn the meaning and spelling of roots, prefixes, and suffixes commonly used 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 books will add hundreds of words to your students' vocabulary and greater depth to their thinking and writing.
