Experiencing Mathematics: Activities to Engage the High School Student is the result of the collaborative effort of nine Adolescent Young Adult (AYA) National Board Certified Teachers (NBCTs) in mathematics. This student edition is a compilation of successful activities that prompt high school students to explore, conjecture, and reflect on their mathematical adventures--thus "experience" mathematics. The relevant nature of the activities will motivate students to pursue their investigations with vigor and take the intellectual risk necessary to construct knowledge and improve problem-solving competence. This book provides student activities grouped in algebra, geometry, and algebra 2 sections that parallel the traditional sequencing in major texts. Through activity design, students are lead through an inductive inquiry in which they conjecture, formulate, and test ideas and concepts. This inductive student-centered approach to learning will not only excite students but also increase student effort.
