This resource includes **50 black-line masters** plus teaching tips, sample problems, answer keys, and reproducible answer sheets. Mathercise™ takes 10 - 15 minutes and includes one reasoning exercise, one solving exercise, one sketching or graphing exercise, and space for a review exercise of your own design. The solving exercises involve percentages, algebra, equations, averages, proportions, probability, and, in Books D and E, functions and analytic geometry. The first few minutes of class is the perfect time to sharpen skills and provide additional practice. Use the activities with a projector, or make copies for your students.
