By David B. Spangler. 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. This workbook, which contains all the handouts in the teacher's edition (sold separately), allows teachers to conveniently collect a student’s work. Grades 6–9.
