Mathimagination • new edition 
series went out of print, Marcy Mathworks republished all six books in one binder with index dividers to separate them. We moved the answers and puzzle punchlines from the pages to an answer section at the end of each book. This is the "new edition". Mathimagination pioneered many of the puzzle formats that were used later in the Pizzazz series books, also published by Creative Publications, and our current Punchline series books. Formats were designed to provide practice for a wide range of mathematical topics, as you can see by looking at the Table of Contents. Certain features are designed into these formats to make this practice more effective. CAREFUL EXERCISE SELECTION. Exercises are sequenced to guide students in incremental, stepbystep fashion toward understanding of the concept or procedure involved. Students practice through an appropriate range of applications for the topic, and important variations and discriminations are highlighted. Exercise sets are designed to be challenging but doable, though the amount of instruction required will vary with the experience of the students.

KNOWLEDGE OF RESULTS. Students need feedback and confirmation when they work, especially when learning new skills. Built into Mathimagination puzzles are various devices for giving the student immediate feedback as exercises are completed. For example, if an answer is not in the scrambled answer list or code, (s)he knows it is incorrect. The student can try again or ask for help. Teachers are able to spend more time helping students who need help and less time confirming correct answers. Students work with greater confidence. MOTIVATING GOALS FOR STUDENTS. Each Mathimagination puzzle has a goal for the student, such as decoding the answer to a riddle or creating a drawing. This goal acts as an incentive, because students do not discover it until they do the exercises. Motivation is also enhanced by the enormous variety of puzzle designs and graphics. Finding out immediately after doing each exercise whether their answer is right or wrong helps to keep students working. Ultimately, finding the punchline or other outcome gives the student a satisfying sense of closure and success. Mathimagination includes puzzles for most topics traditionally taught at about the 6th grade level, though there are review puzzles for students still struggling with the basics. The book can, of course, be used with students at any grade level for whom these topics are appropriate. Each puzzle is designed to provide practice for a specific objective listed in the Table of Contents. Many puzzles provide space for student work. And, hopefully, their selfcorrecting feature will lighten the burden of correcting assignments.
