1 A Correlation of 2010 to the Arizona Mathematics Standard Articulated by Grade Level Grades K 6 M/M-159

2 Correlation Introduction This correlation is designed to show the close alignment between Pearson focusmath and the Arizona Mathematics Standards Articulated by Grade Level (2008). Correlation page references are to the Teacher s Edition. Lessons in the Teacher s Edition contain facsimile Student Edition pages. focusmath provides districts and schools with a flexible program to meet any framework. This curriculum can be used in a variety of settings, including before- or after-school programs, summer school, pull-out or resource-room instruction, or tutoring programs. focusmath features concise Steps which target the NCTM Focal Points. Focusing on a smaller number of key skills allows the teacher to spend an extended amount of time on one concept. This strategy provides the student with a deeper understanding of the concept, better mathematical fluency, and the ability to transfer meaningful mathematics to different situations. Teacher s Edition There is one Teacher s Edition per grade, which contains support for all three student books, Teaching Tool Masters, Assessment Masters, and Answer Keys Student Books There are three consumable student books per grade, one for each Focal Point. Students may be recommended for one or more of the books depending on the results of their Program Placement Test. Each student book can be completed in 4-6 weeks Manipulatives The manipulative kits provide students with hands-on learning materials that support in-depth conceptual development
