Teaching and Learning Math


K-12 Mathematics Vision Statement

The Centennial School District will ensure that all students will leave our K–12 education program as global learners ready to apply mathematical skills and to use mathematical problem solving to make sense of the world around them with success and confidence.

Secondary Mathematics Instruction

The Centennial School District is committed to providing a rigorous, research-based, and standards-aligned mathematics curriculum that is student-centered and engaging. Teaching strategies rely on the recommendations of the National Council of Teachers of Mathematics and are based solidly on the methodological research in teaching mathematics. The essential elements of the math curriculum include collaborative mathematical discourse, problem-based instruction, and mixed-spaced practice to support the mastery of mathematics.
