In order to teach mathematics in a way that not only builds math skills but also builds student understanding of mathematics and problem solving, it is important for educators to start to think about how the standards build upon each other and how student progress within the standards builds math fluency throughout the years. In the following Powerpoint presentation, an overview of the Common Core State Standards for Mathematics is given along with a discussion of how the CCSSM can help us with the difficulties James might be facing.
In the previous presentation, the mathematical practices of the CCSSM were discussed. It is important to see what these might look like in a classroom setting. What follows is a series of classroom videos from teachingchannel.org that are all aligned with the CCSSM:

Thinking about the CCSSM, how does the teacher in the video promote the practices? Out of the 6 practices, which ones do you find as the most prominent?

Thinking about James, if he were a student in the classroom scenario you just viewed, how could you offer him additional assistance?
Additional videos are listed below to allow you to view more classroom episodes of the CCSSM practices in action.

While it is important for educators of all students to understand the CCSSM and develop learning opportunities grounding in the Mathematical Practices, most students with disabilities will require a few additional supports to build solid math problem solving skills. You may find it useful to become more familiar with the CCSS for Mathematics before moving to the next portion of this module. Take a few minutes to look over the standards themselves and the progressions. http://www.corestandards.org/Math
