Lesson Objective

Students will demonstrate proficiency in writing, solving, and interpreting multi-step linear equations, including identifying special cases (no solution or infinitely many solutions).

How do we determine if a linear equation has one, none, or infinite solutions?

How can algebraic equations be used to model and solve real-world problems?

8.EE.C.7 (Solve linear equations in one variable)

A summative assessment and review period to evaluate students' ability to solve complex linear equations and apply them to situational contexts (DOK 3).

Confusing "0 = 0" (infinite solutions) with "x = 0" (one solution).

Incorrectly identifying "no solution" when a variable remains (e.g., x=5).

Errors in expanding expressions with the distributive property or collecting like terms.

Provide Equations Review materials for targeted practice.

Small group instruction focused on multi-step equations with fractions and decimals.

Use of visual aids or manipulatives for solving equations with variables on both sides.
