2 Introduction The Correlation of Connected Mathematics 2 (CMP2), 7 th Grade Units 2009 to the Oregon Mathematics Content Standards for Grade 7, demonstrates the alignment of content between CMP2 and the Oregon Mathematics Content Standards. This document contains references from the Teacher Guides (TG) and Student Editions (SE) to the relevant standards in Grade 7. Additional Topics that will be available on Pearson SuccessNet were added to this correlation to further enhance the alignment of CMP2 to the Oregon Mathematics Content Standards. As part of the CMP2 program, teachers also have these resources to draw from for professional development, support for parents and students, assessment, and practice. Additional CMP2 Teacher Resources include: Implementing and Teaching Guide, Strategies for English Language Learners, Parent Guide, Special Needs Handbook, Teaching Transparencies, Grade 7 Additional Practice and Skills Workbook, Grade 7 Assessment Resources, Additional CMP2Technology Resources include: StudentEXPRESS CD-ROM, ExamView 6.0 Test Bank CD-ROM, TeacherSTATION (includes Teacher Express, MindPoint QuizShow and Presentation Resources), Teaching Middle Grades with TI Technology, Success Tracker, and pearsonschool.com The National Science Foundation funded Connected Mathematics Project between 1991 and 1997 to develop a middle school mathematics program. That program, Connected Mathematics, was a complete mathematics curriculum to help students develop understanding of important concepts, skills, procedures, and ways of thinking and reasoning in number, geometry, measurement, algebra, probability, and statistics. The National Science Foundation funded a revision of Connected Mathematics in This revision, CMP2 took advantage of lessons learned in the six years that the first edition was used in classrooms. With the introduction of CMP2, it is important to note that for more than five years, the authors worked to build on the solid foundation already established by the first CMP and the research supporting the program. Research has been the central, guiding force in the product development process. Authors and product developers relied on the efficacy data for making improvements in design and content, resulting in an even more effective program. Fifteen sites, with varying characteristics that are representative of schools across the nation, participated in three rounds of revisions for each grade level. Input from more than 15,000 students and 300 teachers was integrated into CMP2. CMP2 has already proven to support student learning, helps students to develop and maintain their skills, and enhances their mathematical thinking and reasoning. Connected Mathematics 2 provides 24 Student Units (8 per grade level). Every unit develops a big mathematical idea, important clusters of related concepts, skills, procedures, and ways of thinking. Students develop understanding of algorithms and strategies for computing and estimating in a variety of ways. They learn to recognize when an algorithm or strategy applies to a new context and when they can build on the skills and strategies they know in order to develop new strategies. In these processes, students practice skills as an ongoing activity throughout the curriculum. In addition, Connected Mathematics 2 helps students develop algebraic reasoning. The program aims to expand student views of algebra beyond symbolic manipulation and offers opportunities for students to apply algebraic reasoning to problems in many different contexts throughout the course of the curriculum. 1
