California Standards for Mathematics adopted in 2010 and modified in 2013 include both content and process standards. Content standards for K-8 are organized according to domains and higher mathematics standards by conceptual categories that make up model courses. The K-12 Standards for Mathematical Practice (MP) address “habits of mind” that students should develop to foster mathematical understanding. These are integral to supporting students’ mathematical understanding. Both types of standards must be implemented to have full impact of the California Standards for Mathematics.
