Mathematics Standards Review

A strong mathematics education depends upon a clear understanding of its interrelated concepts, skills and practices to ensure students are on the pathway to success in their academic careers. The knowledge and skills students need to be prepared for mathematics in college, career, and life are woven throughout the K-12 mathematics standards.

The mathematics standards are broken into a variety grade bands (ie K-2, 3-5,K-5, 6-8, High School) with standards grouped as clusters within domains. Although domain names change as the standards build through K-12, they can be organized by the following clusters:

  • Quantitative Reasoning: Counting and Cardinality (K), Number and Operations in Base Ten (K-5), Number and Operations Fractions (3-5), Ratio and Proportional Relations (6-8), The Number System (6-8), and Number and Quantity (High School).
  • Algebraic Reasoning: Operations and Algebraic Thinking (K-5), Expressions and Equations (6-8), Functions (8-HS), and Algebra (HS)
  • Geometric Reasoning: Geometry (K-12)
  • Statistical Reasoning: Measurement and Data (K-5), Statistics and Probability (6-HS)
  • Mathematical Practices (K-12): Make sense of problems and persevere in solving them;  Reason abstractly and quantitatively;  Construct viable arguments and critique the reasoning of others; Model with mathematics; Use appropriate tools strategically; Attend to precision, Look for and make use of structure and look for; and Express regularity in repeated reasoning.
