Pre-Algebra

This revision designed for a bridge course between arithmetic and elementary algebra, provides thorough coverage of arithmetic while simultaneously introducing algebra skills. The link between arithmetic and algebra is continually shown. Students are encouraged to develop critical thinking skills, strategies they need to succeed in this course and subsequent mathematical courses, and overall confidence with math. A unique, spiral organization provides coverage that details essential skills for each set of numbers - from whole numbers through rational numbers and integers, Chapter opening applications help students see math in the natural world around them, "Group Activities" promote cooperative learning and "State Your Understanding" exercises sharpen students' writing skills. Each example is worked out with a step-by-step, written explanation provided alongside in a "Strategy" column. "Warm-up" problems, immediately following the examples, actively involve students in the learning process. Scientific calculator exercises have been added, in keeping with NCTM guidelines. Realistic 3-D art helps students visualize application problems and mathematical concepts while "Cumulative Review Tests" after Chapters 3, 6, and 9 reinforce students' grasp of the material and allow self-assessment of progress.
