Implement the Mathematics Standards with CDE's Professional Learning Modules

CDE recommends that schools and districts take a patient, planned approach to implementing the 2020 Colorado Academic Standards. The two-year transition period between the adoption of these standards in 2018 and their implementation in the 2020-2021 school year offers Colorado educators the opportunity to give standards implementation the full attention it deserves.

To assist in these efforts, the Office of Standards and Instructional support is providing a series of professional learning modules to help school leaders facilitate standards implementation efforts with their staffs. The first phase of modules focuses on disciplinary and standards literacy, which establishes a foundation for understanding the relationship between disciplinary content and the educational purposes of standards. The second phase of modules focus on curriculum and resource alignment and ends with goal-setting for district- and school-level curricular changes. The final phase of modules will focus on connecting the standards to instructional practices and strategies.

Academic Standards

The mathematics standards compel us to make mathematics relevant to students by moving beyond mere answer getting to doing the work of mathematicians. The standards emphasize the development of students’ abilities to use mathematics to represent their lived experiences and to simplify and explain complex phenomena.

Curriculum Support

Article IX, Section 16 of Colorado's constitution states, "Neither the general assembly nor the state board of education shall have power to prescribe textbooks to be used in the public schools." However, CDE can still serve as an advisor to help districts and schools adopt, adapt, develop, or use the materials of their choice.

Instructional Support

Colorado's Constitution prohibits CDE from requiring or recommending curricular materials, but we can still be advisors that help districts and schools adopt, adapt, develop, or use the materials of their choice.

Best, First Instruction

Best, First Instruction gives all students the best opportunity to learn standards-based, grade-level content and skills the first time they receive instruction.

Supporting Struggling Learners in Mathematics

  • Resources include a guide from the What Works Clearinghouse, Colorado's English Language Proficiency Standards, and materials to support emerging bilingual learners of English.
