ALGEBRA: class 9

by Jeffrey Collins

ALGEBRA class 9 The book follows a step-by-step teaching approach and explains definitions and examples clearly, just as a teacher would explain them in the classroom. Examples and exercises are designed to encourage students to think for themselves. In addition, the text uses a variety of types of proof (paragraph, flow chart, and two-column, with explanations) to give students more practice in understanding proofs and in writing their own. At each stage of the course, students' progress can be checked through regular self-check ('Check Yourself) sections and graded exercises (see the section 'Using This Book' at the end of this preface for more information) Separate activity and project sections have also been provided, to help increase students' understanding of the topic as they study The book ends with a summary of the main points in the module, as well as review tests on all of the sections to help prepare students for examinations.
