"CCSS Mathematics: K-12 Standards for Mathematical Practice"
This free professional learning module from the California Department of Education provides six units of instruction on the Standards for Mathematical Practice. It is designed for all levels, and at several points along the way you can choose an elementary, middle school, or high school perspective o explore a particular practice. It's the most detailed, quality training I've seen on the subject.
