This module assumes that the information presented in previous modules is well known to the learner. Module 6 is the third of three modules (4, 5, and 6) designed to provide an in-depth look at the Standards of Mathematical Practice which are part of the Common Core State Standards for Mathematics. Module 6 focuses on strategies for implementing the practices in the classroom, determining the degree of students' progress towards meeting the practices, and using an observation tool to ensure that practices are evident in a classroom. Course Objectives: By the end of the module, the learner will be able to: (1) understand how to determine the progress that a student is making in meeting a practice; (2) state how specific instructional strategies are used to promote the use of practices and increase student achievement; and (3) use an observation tool to identify ways to make math practices visible to observers in the classroom and to assist in understanding the meanings of the practices.
