Core-Plus Mathematics is a standards-based, four-year integrated series. Concepts from algebra, geometry, probability, and statistics are integrated, and the mathematics is developed using context-centered investigations. Developed by the Core-Plus Math Project at Western Michigan University with funding from the National Science Foundation (NSF). The first three courses in Core-Plus Mathematics provide a significant common core of broadly useful mathematics for all students. They were developed to prepare students for success in college, in careers, and in daily life in contemporary society. The program builds upon the theme of mathematics as sense-making. Through investigations of real-life contexts, students develop a rich understanding of important mathematics that makes sense to them and which, in turn, enables them to make sense out of new situations and problems. Reading age for native speakers: High School students

NB: Course 1 and Course 2 are not included in this Interactive Edition since they are already available on ET.
