Word Roots teaches students the meanings of prefixes, roots, and suffixes commonly used in English. Learning word elements dramatically improves spelling and the ability to decode unfamiliar words. Word Roots will add hundreds of words to your students' vocabulary and greater depth to their thinking and writing. For each lesson students first learn the meanings of prefixes, roots, and suffixes. Then they: - divide known and unknown words into their elements or assemble elements to form whole words. - match word parts or whole words to their definitions by analyzing their meanings. - apply their new vocabulary in sentences.
