#### 6.6

Expressions, equations, and relationships. The student applies mathematical process standards to use multiple representations to describe algebraic relationships. The student is expected to:

(A)  identify independent and dependent quantities from tables and graphs;

(B)  write an equation that represents the relationship between independent and dependent quantities from a table; and

(C)  represent a given situation using verbal descriptions, tables, graphs, and equations in the form y = kx or y = x + b.

#### 6.7

Expressions, equations, and relationships. The student applies mathematical process standards to develop concepts of expressions and equations. The student is expected to:

(A)  generate equivalent numerical expressions using order of operations, including whole number exponents and prime factorization;

(B)  distinguish between expressions and equations verbally, numerically, and algebraically;

(C)  determine if two expressions are equivalent using concrete models, pictorial models, and algebraic representations; and

(D)  generate equivalent expressions using the properties of operations: inverse, identity, commutative, associative, and distributive properties.

#### 6.8

Expressions, equations, and relationships. The student applies mathematical process standards to use geometry to represent relationships and solve problems. The student is expected to:

(A)  extend previous knowledge of triangles and their properties to include the sum of angles of a triangle, the relationship between the lengths of sides and measures of angles in a triangle, and determining when three lengths form a triangle;

(B)  model area formulas for parallelograms, trapezoids, and triangles by decomposing and rearranging parts of these shapes;

(C)  write equations that represent problems related to the area of rectangles, parallelograms, trapezoids, and triangles and volume of right rectangular prisms where dimensions

are positive rational numbers; and

(D)  determine solutions for problems involving the area of rectangles, parallelograms, trapezoids, and triangles and volume of right rectangular prisms where dimensions

are positive rational numbers.

#### 6.9

Expressions, equations, and relationships. The student applies mathematical process standards to use equations and inequalities to represent situations. The student is expected to:

(A)  write one-variable, one-step equations and inequalities to represent constraints or conditions within problems;

(B)  represent solutions for one-variable, one-step equations and inequalities on number lines; and

(C)  write corresponding real-world problems given one-variable, one-step equations or inequalities.

#### 6.10

Expressions, equations, and relationships. The student applies mathematical process standards to use equations and inequalities to solve problems. The student is expected to:

(

A)  model and solve one-variable, one-step equations and inequalities that represent problems, including geometric concepts; and

(B)  determine if the given value(s) make(s) one-variable, one-step equations or inequalities true.
