This website engages educators in learning more about the Common Core Standards for Mathematical Practice and how they can be connected to the content standards. Use the Illustrations, centered on student dialogues, to see the Mathematical Practices (MPs) in action. The Implementing the Mathematical Practice Standards team is also developing a professional development curriculum to support learning about the Common Core Standards for Mathematical Practice for Grades 5-10 mathematics teachers. This professional development experience will be centered on the use of the Illustrations found on this website. If you are interested in learning more about participating in or leading this professional development program in your area during 2013–2014 or 2014–2015 as part of the field testing of the professional development materials, please contact firstname.lastname@example.org.
