## Reflection: Staircase of Complexity Graphing Parallel and Perpendicular Lines (Day 1 of 2) - Section 2: Guided Notes + Practice

I take a methodical approach to what I want students to do in order to make my problem sets, so while the time varies because the problem sets can vary in number and in skill, my approach allows it to not have to take too unnecessarily long. For example, I will build the equation with the specific values I want them to use first and then develop an associated word problem based on the answer. This is a very useful application of the backward design.

Unit 5: Graphing Linear Functions
Lesson 5 of 7

## Big Idea: Through graphing students will deduce that the slopes of parallel lines are the same and the slopes of perpendicular lines are opposite reciprocals.
