Bob Books Sight words are words that must be recognized by sight rather than sounded out. They are the most frequently used words in the English language, such as are, was, and out. Children who are learning to read are encouraged to practice and memorize this list of words, in order to become fluent readers (who are able to read for meaning rather than stumble over words). Sight words are taught primarily in kindergarten and first grade, though often the practice extends up through fourth grade.BOB BOOKS have always incorporated sight words, though the sounding-out approach minimized their use. These will be the first BOB BOOKS products to focus on learning and practicing sight words. They will stand alone as two boxes - neither MY FIRST, nor numbered as a SET. Their noted grades (kindergarten or first) will serve as the level. The titles allow parents to choose whether to prepare their children for next year, or reinforce what they"ve learned last year.
