Learning goals: Teacher Facing Categorize (orally and in writing) linear equations in one variable based on their structure, and solve equations from each category. Describe (orally and in writing) features of linear equations that have one solution, no solution, or many solutions. Describe (orally) strategies for solving linear equations in one variable with different features or structures. Full lesson plan (warm-up, activities, synthesis, cool-down prompt) from 8.4 Linear Equations and Linear Systems, Grade 8.
