Download the 2-page printable 3 Act Math Tip Sheet to ensure that you have the best start to your journey using 3 Act math Tasks to spark curiosity and fuel sense making in your math classroom! Day 1 : The Desmos activity I created for this unit explored standard, slope-intercept, and transformation (vertex) form. Thanks! I am confused on how it fits and folds together. 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. Orient the paper so the words “Two angles are Corresponding angles when…” are in the top left corner. In grade 9 academic, it might be a good idea to ask the group what it means for two lines to be parallel or perpendicular. Copy the pages (1 and 2 if they aren’t filling them out or 2 and 3 if they are) back to back.

Enter your email to receive resources, tasks, tips, and more straight to your inbox weekly! I was just trying to get a copy of the Knowledgehook gameshow that goes along with this activity. 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. They then identify and measure corresponding, alternate interior, alternate exterior, and consecutive interior angles and make conjectures. Write the equation in slope intercept form. Watch the video (Parallel & Perpendicular Slopes: Level 3) 2. I usually ask students to share out who feels confident in their original guess and who wants to update their prediction. Learning Goal: Build procedural fluency with determining equations of parallel and perpendicular lines. 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 If you have already used the Walk Out 3 Act Math Task with your class, you could probably just show this image: Ask students what they wonder? Bleh. She was the Director of Training at Managed.com for four years. Identify your learning targets for the activity. Parallel and Perpendicular lines – Desmos. This is the first time those concepts come up in the math curriculum in Ontario, so I never assume everyone has an understanding. The “copy it” link doesn’t seem to be working. How do you know? 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. One boy clasps his hands together like he’s praying. Slope-intercept form: y=mx+b y-intercept is the b and m is slope (gradient) 1. They do. Fold top down and bottom up so they meet in the middle. Take the Schoology Quiz (Concept 8: Level 2) Score of 4 or higher move to level 3 Score of 3 or less, complete the Level 2 Review Level 3 1. 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. What questions come to mind? In general, you can skip the multiplication sign, so `5x` is equivalent to `5*x`. I’m Kyle Pearce and I am a former high school math teacher. What will you discuss on those screens? In the past, creating an activity using multiple Desmos graphs involved linking a series of graphs from one to the other. K - University grade. Thanks for the great resources, they have been life savers! Use the Types of Lines Foldable to distinguish between them. Use the Angles Formed by Transversal Foldable to master the vocabulary. Desmos Activity Builder [Try It | Copy It] 4.Distribute the Slopes of Parallel and Perpendicular Equations of Lines activity sheet. Slope=rise/run=(y2-y1)(x2-x1) 2. Point-slope form: y-y1=m(x-x1) can write this using the slope and one point on the line. Give students two lines with the same slope in slope/y-intercept form; Give students two lines with negative reciprocal slopes in slope/y-intercept form. 4. The calculator will find the equation of the parallel/perpendicular line to the given line, passing through the given point, with steps shown. Free perpendicular line calculator - find the equation of a perpendicular line step-by-step This website uses cookies to ensure you get the best experience. Stacie Bender taught high school mathematics and technology courses for 17 years. Thanks so much for the wonderful website! Write an equation that is parallel to the line y = x - 5 through (1, -2) Preview this quiz on Quizizz. Then, I had to play around with the sliders and figure out how to make lines parallel and perpendicular to it. Parallel and Perpendicular Lines DRAFT. By using this website, you agree to our Cookie Policy. M: What do you know about parallel lines? Classwork Estimation - Fjellstua Viewpoint Desmos Activity Unpack upcoming Concept Quiz Spiraling Practice 1:1 Lesson GoFormative for spiraling Answers Link to Answers Standards Common Core HSG.GPE.B.5 – Prove the slope criteria for parallel and perpendicular lines … Edit. Perpendicular lines do not have the same slope. Hi Kristen! 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. Parallel and Perpendicular Lines Investigation Name _____ Go to s t u d e n t . While parallel and perpendicular lines will be the primary focus of this chapter, there are other types of lines. Using Context to Introduce Parallel, Perpendicular or Neither. Write the equation in slope intercept form. In this activity, students use sliders to investigate the slopes of parallel and perpendicular lines. Press Now graph 2 other lines parallel to the first. Here’s all the links in one convenient spot for this activity to go off without a hitch: Act 1 [video] Google Classroom Facebook Twitter Act 3 [scene 1 video | scene 2 video (optional) | scene 3 video (optional)] The slope of one line is the negative reciprocal of the slope of the other line. by Bob Lochel. Desmos Introduction Open Safari and go to Desmos.com. They then create their own so they can verify if they were correct or not. At the very end there is a card sort for parallel, perpendicular and neither. Took quite a bit of time and planning. I started my unit for Parallel Line proofs by exploring parallel and perpendicular lines algebraically.
