Introduction

This document provides pacing and other information for Chicago Public School teachers and administrators in schools that use Connected Mathematics 2 (CMP2) in grades 6-8. Connected Mathematics 2 is the elementary school math curriculum developed at Michigan State University and published by Pearson Prentice Hall. This document should be used along with the Teachers Guide that is part of CMP2. It does not replace the detailed information found in the Teachers Guide. The order of some lessons has been changed to provide students with content experiences prior to the Illinois Standards Achievement Test (ISAT). The content in some lessons prepares students for mathematics concepts covered in depth in later grades; therefore, these lessons may not include a reference to the grade level Illinois Assessment Framework (IAF) but are critical in developing a students understanding of the mathematics. Some Grade 7 units are used in Grade 8. The detailed GPSA includes the applicable Grade 7 IAF statements for each lesson and the numbers (in parentheses) to the corresponding Grade 8 IAF statements. Teachers are advised to use the Summary Pacing Guide (page iv) and the detailed Guide to Pacing and Standardized Assessment (that follows) to develop their own pacing for the year. Pacing should be based upon 60 minutes of mathematics per day. All Connected Mathematics 2 units address the content and process standards: Numbers and Operations Problem Solving Algebra Reasoning and Proof Geometry Communication Measurement Connections Data Analysis and Probability Representation A high fidelity implementation of Connected Mathematics 2 incorporates the use of all components of the math curriculum: Investigations ACE Questions Mathematical Reflections Assessments This document can be useful in several ways. It can help teachers: In their pacing so they cover the concepts required for that particular grade level and help them get through the curriculum by the end of the school year. This guide provides a reasonable schedule for completing CMP2 lessons within the CPS calendar. Use CMP2 to address the Illinois Learning Standards. See the connections between the lessons, the Illinois Learning Standards and the Illinois Assessment Frameworks. See the connection between CMP2 lessons and items that may appear on standardized tests. Making this connection explicit emphasizes that the most effective preparation for a standardized test is to do a good job teaching a high-quality math curriculum that is aligned with the standards the test is assessing. We look forward to feedback from teachers who will be using this document during the 2010-2011 school year.
