Teach your child how to solve five kinds of analogy problems with these Ridgewood Analogies workbooks. Each kind of analogy is studied at four skill levels, from finding an analogy that corresponds to a given analogy, to creating two analogies that correspond to one another in a given relationship. Subject matter used for the analogies is drawn from across the curriculum rather than only vocabulary as is true of some analogy resources. There are five books in the series, suggested for use with grades four through eight respectively.
