Introduce Parallel and Perpendicular Lines

  1. Teach students to construct parallel lines and perpendicular lines (at a point on a line and from a point to a line). Topics include:
    Constructing Parallel and Perpendicular Lines
    Slopes of Parallel and Perpendicular Lines
  2. Team members share key facts and observations, and begin to synthesize information into draft ideas for their house.
  3. If time permits, teams share ideas using the Does It Fit? Visible Thinking Routine.

Tips and Tools

Use Sketchometry or Geometer’s Sketchpad to help students practice constructions. Both are tools for use with geometry.

Have students enter their observations (what they learned, what they need to learn, etc) in their Daily Learning Logs.
