    • Instructional time should focus on four critical areas:  

       

      • developing understanding of and applying proportional relationships:
      • developing understanding of operations with rational numbers and working with expressions and linear equations;
      • solving problems involving scale drawings and informal geometric constructions, and working with two- and three-dimensional shapes to solve problems involving area, surface area, and volume; and
      • drawing inferences about populations based on samples.

      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.
