### General Information

**Subject Area:**Mathematics

**Grade:**912

**Domain-Subdomain:**Algebra: Reasoning with Equations & Inequalities

**Cluster:**Level 3: Strategic Thinking & Complex Reasoning

**Cluster:**Understand solving equations as a process of reasoning and explain the reasoning. (Algebra 1 - Major Cluster) (Algebra 2 - Major Cluster) -

Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.

### Test Item Specifications

**Assessment Limits :**

Items will not require the student to recall names of properties from memory.

**Calculator :**

Neutral

**Clarification :**

Students will complete an algebraic proof of solving a linear equation.

Students will construct a viable argument to justify a solution method

**Stimulus Attributes :**

Items should be set in a mathematical context. Items may use function notation.

Items should be linear equations in the form of ax + b = c, a(bx + c) = d, ax + b = cx + d, or a(bx + c) = d(ex + f), where a, b, c, d, e, and f are rational numbers. Equations may be given in forms that are equivalent to these.

Coefficients may be a rational number or a variable that represents any real number.

Items should not require more than four procedural steps to reach a solution.

**Response Attributes :**
