    • Instructional time should focus on three critical areas:

       

      • formulating and reasoning about expressions and equations, including modeling an association in bivariate data with a linear equation, and solving linear equations and systems of linear equations;
      • grasping the concept of a function and using functions to describe quantitative relationships;
      • analyzing two- and three-dimensional space and figures using distance, angle, similarity, and congruence, and understanding and applying the Pythagorean Theorem

      Mathematical Practice Standards 

       

      1. Make sense of problems and persevere in solving them.
      2. Reason abstractly and quantitatively.
      3. Construct viable arguments and critique the reasoning of others.
      4. Model with mathematics.
      5. Use appropriate tools strategically.
      6. Attend to precision.
      7. Look for and make use of structure
      8. Look for and express regularity in repeated reasoning.
        9.
