This video from The Teaching Channel shows a teacher implementing a portion of the Formative Assessment Lesson, "Sorting and Classifying Equations" from the Shell Center Site.
To reinforce and honor the language of the standards, we have directly correlated the mathematical practice standards to excerpts of mathematics lessons. Just as with content standards, not every lesson reflects all elements of the individual standards for mathematical practice. By representing examples from different classrooms for each standard, we also want to emphasize how many different ways teachers may enact these standards for mathematical practice in their classrooms, with their particular learners. While there is no one "right way," there are multiple examples of successful strategies to launch and sustain these practices. Click the individual standards below to see instances of the practice standards in classroom lessons. Although the practices are presented here individually, it's important to keep in mind that the practices can, and should, be evident together in a lesson. See the Exemplary Lessons Integrating the Standards for Mathematical Practicefor a holistic view of the practices together.
