Here's the perfect introduction to higher order thinking skills. In addition to expanding vocabulary, these challenging little word puzzles provide fundamental instruction in critical thinking. Two-color illustrated worktexts feature thorough "how-to" instructions, plenty of helpful examples, and useful tips and reminders. Progress tests are included at the middle and end of each worktext. Teaching tips and answer keys are provided in separate Teacher Note CDs. Book 2 contains slightly more challenging analogies. Each Worktext Includes over 500 analogies in 18 categories: synonyms, antonyms, characteristics, cause/effect, sequence, part/whole, member/group, degree, grammar, and many more.
