## common core state standards for mathematical practice

Inside Mathematics illuminates the mathematical practice standards with video 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 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 Mentors of Mathematical Practice for a holistic view of the practices together.
