This course is part of a 3 year series aimed at preparing students for success in 9th grade algebra. The primary text for this progression is Core Connections by College Preparatory Mathematics. Grade 7 math uses the second course in the series.

*From the authors:*

Core Connections, Course 2is the second of a three-year sequence of courses designed to prepare students for a rigorous college preparatory algebra course.On a daily basis, students in

Core Connections, Course 2use problem-solving strategies, questioning, investigating, analyzing critically, gathering and constructing evidence, and communicating rigorous arguments justifying their thinking. Students learn in collaboration with others while sharing information, expertise, and ideas. The course helps students to develop multiple strategies to solve problems and to recognize the connections between concepts. The lessons in the course meet all of the content standards and embed the “Mathematical Practices” of the Common Core State Standards released in June 2010. (CPM)
