What are your chances of winning the lottery? How much interest will you end up paying on that credit card purchase? Thought-provoking real-world math problems (and some humorous ones too) require inductive and deductive reasoning as students search for a pattern, break a code, uncover and correct errors, or use clues to solve a mystery. Teacher pages set up full instructions for 27 activities driven by reproducible student handouts and correlated to NCTM standards. A workbook containing all the handouts allows teachers to conveniently collect a student’s work. Grades 6-9. Bibliography. Answer keys with full solutions. Good Year Books. 199 pages. Second Edition.
