Teacher Move: It should be noted that my intention with the video/image is that the lines do appear to be perpendicular, but the scale on the x- and y-axis’ are not equivalent. Here are a couple more videos you might want to show as they change the scale to 1:1, but aren’t necessary: While many math teachers have been using the very powerful Desmos Graphing Calculator, the new Desmos Activity Builder is an awesome way to leverage the power of Desmos in a more structured activity.

When two lines are cut by a transversal, there are special names for the angles formed by the transversal and the lines. Using Context to Introduce Parallel, Perpendicular or Neither. cdodd. Slope-intercept form: y=mx+b y-intercept is the b and m is slope (gradient) 1. Each group should receive a copy of the Card Set: Equations (already cut up). Just updated the link. In my geometry course, we explore the geometric and algebraic aspects of almost every unit. The All About Slope Foldable can help you calculate slope given two points, find an equation in slope y-intercept form, use point slope form to find equations, and includes the relationships between parallel and perpendicular lines and their slopes. I first entered the function y = 2x +3, a simple linear equation. All of the lines shown in the graph are parallel because they have the same slope and different y-intercepts.. Lines that are perpendicular intersect to form a [latex]{90}^{\circ }[/latex] angle. Google Classroom Facebook Twitter The slopes of parallel lines are equal, and the slopes of perpendicular lines are opposite reciprocals. 1393 times.

Anticipate screens where students will struggle, then plan your response. We can show that two lines are perpendicular if the product of the two slopes is [latex]-1:{m}_{1}\cdot {m}_{2}=-1[/latex]. Your email address will not be published. What are some examples? Use the Geogebra activity below to explore the relationships between the special angles above when the lines that are cut by the transversal are parallel. When distance-time graphs came up in my course, I created the Walk Out tasks and finally found a way to at least spark the conversation about parallel and perpendicular lines. This 3 act math task was created using video clips from the Walk Out 3 Act Math Task as a way to get students wondering about parallel and perpendicular lines.

Exploring Parallel and Perpendicular Lines Pencil Paper Activity will be used to learn how the slopes of parallel and perpendicular lines are related for those who don’t want to use technology. It was only because the scale was changed (arbitrarily) that they became non-parallel … so I feel like it is just a sneaky arbitrary “trick” which makes the students intuitive guess incorrect. Parallel and Perpendicular Line Calculator. The Making Math Moments That Matter Podcast Is LIVE! Give students more time to discuss and share out. Desmos Introduction Open Safari and go to Desmos.com. In general, you can skip the multiplication sign, so `5x` is equivalent to `5*x`. Required fields are marked *. While parallel and perpendicular lines will be the primary focus of this chapter, there are other types of lines. 3) Create a line perpendicular to the given line. At the very end there is a card sort for parallel, perpendicular and neither. Have students work in groups of two or three. The Geogebra activity below helps underscore the fact that the distance from a point to a line is the length of the perpendicular segment from the point to the line. The calculator will find the equation of the parallel/perpendicular line to the given line, passing through the given point, with steps shown. Press Launch Calculator Press Show Keypad Type (use the symbol to write 2/5). “5 feet = 1 second” scale, the lines *were* parallel originally. Helping K-12 teachers spark student curiosity, fuel sense making in kids, and ignite the teaching moves necessary to lead successful problem based mathematics lessons. by cdodd. K - University grade. Hi Stacie, You can grab it here too: https://app.knowledgehook.com/app/Teacher/903465b0-b5c1-e811-a95d-000d3af32666/Content/1e8176f0-c8af-e511-80ed-00155dd5c401//View, If I understand correctly, the non-parallel-ness of the lines is just due to the scale on the axes … but one axis is feet and one is seconds, so there is no apriori scale relating the two axes … since the original picture was clearly using Edit. This gives the viewer the impression that the lines are parallel, but as you’ll see in the next few videos/images, they are not. Log InorSign Up. Here’s some screenshots from the Desmos Parallel and Perpendicular Lines Activity Builder Activity: After students finish the Desmos Activity Builder Activity and you’ve taken some time to consolidate the new learning about parallel and perpendicular lines, students can now work on some practice to reenforce the new learning.

I’ve been doing something similar to this for about 10 years and while it does appropriately address the parallel and perpendicular portions of the expectation through investigation, it felt more like I spoon fed the investigation a bit too much. Identify your learning targets for the activity. For Investigation 3, I played around with how functions can be parallel and perpendicular to one another. Parallel Lines and Transversals Section 3.2notes, Proofs with Parallel Lines Section 3.3notes. 69% average accuracy. Then, I had to play around with the sliders and figure out how to make lines parallel and perpendicular to it. Exploring Parallel Lines and a Transversal download.
