The simple innovation of these books makes learning logic possible for every level of ability. Each puzzle (46 to 48 per book) categorizes information and lists clues. By using the "cross-out-and-circle”technique, students will practice logical thinking. As part of the curriculum, have students solve 2 to 3 puzzles a week. This allows them to integrate logic into their thinking and transfer it to all subject areas. Students, by practicing the process of elimination, can also prepare themselves for standardized test which reward logical thinking. Answers provided. Reproducible. Solutions included.
