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.
