Word Roots teaches students the meanings of Latin or Greek 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 children's' vocabulary and greater depth to their thinking and writing. For each lesson, students first learn the meanings, 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; and apply their new vocabulary in sentences. Includes a pretest/posttest, answers and a dictionary of words derivations. Features 72 activities in 112 pages. Paperback by Cherie Blanchard. For grades 3-4.
