Lesson 5: Module Review & Test
Duration of Days: 4
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.
