Linear Functions Practice Set for Grade 8
A skill-by-skill practice packet for 8th graders covering rate of change from points and tables, graphing and writing linear equations in slope-intercept, point-slope, and standard forms, graphing linear inequalities, modeling with y = mx + b, and finding x- and y-intercepts. Each section opens with a worked example and key concept box before moving into independent problems.
Teacher Guide & Tips
- Use the sections as separate mini-lessons or station rotations, starting with rate of change (Skill 1) before moving to equation forms, since later skills build on finding slope.
- Discussion question: Why does the rate of change come out the same no matter which two points from the same line you choose?
- Scaffold for struggling readers: have them label (x₁, y₁) and (x₂, y₂) on the table or graph before writing the formula, and use a sentence frame like "The y-value changes by ___ when x changes by ___."
- Extension for advanced students: ask them to convert an equation given in standard form to slope-intercept form and explain how the intercepts appear in each version.
- Plan roughly 15-20 minutes per skill section, or about 45-60 minutes for a single focused session on one or two skills.
