Lesson Prep

Lesson Details

  • Duration: 50 minutes

  • Learning Goal: Build procedural fluency with determining equations of parallel and perpendicular lines.

Prework

  • Make sure you have Chromebooks or some other class set of technology

  • Read Nora Oswald's Bucket of Lies to prepare for activity

  • Cut out class sets of cards and gather "buckets" for Bucket of Lies activity

Answer Keys

Classwork

1:1 Devices Version

  • Bucket of Lies on paper

  • GoFormative for Practice/Spiraling

Standards

Common Core

  • HSG.GPE.B.5 – Prove the slope criteria for parallel and perpendicular lines and use them to solve geometric problems (e.g., find the equation of a line parallel or perpendicular to a given line that passes through a given point).

TEKS

  • G.2(B) – derive and use the distance, slope, and midpoint formulas to verify geometric relationships, including congruence of segments and parallelism or perpendicularity of pairs of lines

  • G.2(C) – determine an equation of a line parallel or perpendicular to a given line that passes through a given point
