Barrier Analysis and Adaptation for

Intended Learning Outcomes

• Compare and contrast parallel lines and perpendicular lines
• Justify to others why given lines are parallel or perpendicular
• Learn the features of parallel and perpendicular lines

Lesson Outline

• Students in pairs will be given index cards which each have an equations of lines on them
• Students will work together to rewrite the equations in slope intercept form, to identify the slope and intercepts

Continued

• Students will identify which lines are parallel to each other and which are perpendicular
• Students will create a poster showcasing which lines they chose for each category

Continued

• Students will meet with other groups and compare posters
• Groups will take turns justifying their choices on why the lines are parallel or perpendicular
• We will go over answers as a class at the end
