In Grade 8, 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.
