K-12 Mathematics

Arlene Crum
Director of K-12 Mathematics

Washington state formally adopted the Mathematics and English Language Arts K–12 Learning Standards. Assessments for these standards began in the 2014–15 school year.


These standards describe what students should know and be able to do at each grade level.

Supportive Resources


Guidance for Elementary, Middle, and High School in determining the major areas of focus.


The standards were built on progressions: narrative documents describing the progression of learning across a number of grade levels and within a given grade.

Strand documents

Developed by OSPI for educators in all content areas to see the development of conceptual understanding within the strand.

  • Measurement
  • Number Sense
  • Geometry
  • Data and Statistics
  • Fractions

Progression Documents 

  • Developed by Arizona University, these documents are informed both by research on children's cognitive development and by the logical structure of mathematics.

Standards for Mathematical Practice

The Standards for Mathematical Practice describe the mathematical “habits of mind” that mathematics educators at all levels should seek to develop in their students.
