Reflection: Rigor Line It Up! - Section 2: Exploration


In the exploration for this lesson, students are asked to extend their knowledge of parallel and perpendicular lines.  More specifically, at the end of this lesson, students will be able to not only identify parallel and perpendicular lines but also show why lines are parallel and perpendicular using the slope formula.  This second Higher Level Student Example of student work shows a student who understood, after completing the exploration, that parallel lines have the same slope. 

By asking students to answer higher-level questions, that include how and why, it is easier for me as a teacher to understand my students' knowledge.  Furthermore, these higher-level questions, like this other one, Higher Level Student Example are integral to help foster students' writing ability throughout disciplines.

Line It Up!

Unit 2: Line-sanity!
Lesson 6 of 9

Objective: SWBAT write equations of lines that are parallel and perpendicular given slopes and points. SWBAT construct parallel and perpendicular lines.

Big Idea: In this student-centered lesson, students work together to construct parallel and perpendicular lines while also writing equations for these lines.
