Lesson 7: Review and Assess
Duration of Days: 2
Lesson Objective
Students will demonstrate mastery of linear equations in slope-intercept form (y=mx+b) by accurately identifying slopes and y-intercepts, graphing equations across all four quadrants, and interpreting linear parameters in real-world contexts on the unit assessment.
How can you use your knowledge of fractional and integer slopes to verify if your graphed line is mathematically accurate before turning in an exam?
When looking at a multi-quadrant graph on an assessment, what key features (such as intercepts or steepness) help you quickly eliminate incorrect multiple-choice equation options?
Slope-Intercept Form
Linear Function
Parameter
Verification / Substitution
Four-Quadrant Graphing
Mathematical Modeling
8.EE.B.5: Graph proportional relationships, interpreting the unit rate as the slope of the graph. Compare two different proportional relationships represented in different ways.
8.EE.B.6: Use similar triangles to explain why the slope m is the same between any two distinct points on a non-vertical line in the coordinate plane; derive the equation y=mx for a line through the origin and the equation y=mx+b for a line intercepting the vertical axis at b.
Description: A comprehensive review day followed by the administration of the Unit 6 summative exam. Students consolidate everything they have practiced—from counting fractional rise-over-run steps to interpreting initial values—and apply it independently.
Purpose: To evaluate individual student retention, measure the effectiveness of the scaffolding techniques used throughout the unit, and gather actionable data for future intervention.
DOK Level: Level 3 (Strategic Thinking / Assessment).
Test Anxiety Errors: Students rushing and misreading negative signs on slopes or coordinates under test conditions.
Incomplete Verification: Forgetting to substitute a coordinate point back into their written equation to check if their work is structurally sound.
Scaffolding/Support: Provide a reference sheet of basic coordinate plane properties during the pre-test review session. Allow the use of highlighters to isolate parts of word problems.
Extension: Include a bonus or challenge question on the assessment that requires writing a linear equation from a non-linear contextual constraint to preview future functions units.
