Ridgewood Analogies 4 contains an introductory section about how analogies work and some practice exercises. The rest of book 4 is organized by subject areas:
• History and Government
• Language Arts
Students solve analogies in each of these areas, which enable them to use information they are learning in the subject areas. In all exercises, students provide missing terms in analogies and write out a phrase that describes the particular relationship; for example, a bat is used to hit a ball, just as a racket is used to hit a tennis ball.
