Students will love the challenge of solving these interest-grabbing puzzles. Armed with the clues (4–6 per puzzle), they"ll have to pool their past knowledge, check reference material, and, most importantly, think in order to discover the person, place, or thing to which the clues refer. Clues progress from general to specific. Each exercise is a lesson in cultural or global literacy, as well as an opportunity to develop thinking and reference skills. You"ll find a multitude of uses for these motivating riddles. Use them for team competition (or cooperation), weekly challenge, research, or to build thinking skills. These topics build a foundation of information that all literate people should know. Your students will enjoy using these puzzles to expand their knowledge of the world around them while they build important research and thinking skills. Book 2 in this series includes puzzles on: literature (authors and literary works); things (such as blue whales, World War II, United Nations, and hydrogen); mathematics (using clues about place value and number characteristics to determine the correct number); and logic (deductive logic).
