Course Description:

In Grade 8, instructional time will focus on these critical areas:

(1) formulating and reasoning about expressions and equations

• modeling an association in bivariate data with a linear equation
• solving linear equations
• solving systems of linear equations

(2) grasping the concept of a function and using functions to describe quantitative relationships

• a function as a rule that assigns to each input exactly one output.
• functions describe situations where one quantity determines another
• representations and partial representations of functions
• aspects of the function are reflected in the different representations.

(3) analyzing two‐ and three‐dimensional space and figures using distance, angle, similarity, and congruence

• understanding and applying the Pythagorean Theorem;
• translations, rotations, reflections, and dilations
• congruence and similarity to describe and analyze two-dimensional figures and to solve problems
• the sum of the angles in a triangle is the angle formed by a straight line
• angles created when a transversal cuts parallel lines
• the Pythagorean Theorem and its converse
• volume by solving problems involving cones, cylinders, and spheres.
