Begin with the End in Mind The theme or “big ideas� for this PBL: Students will explore parallel lines and transversals. TEKS/SEs that students will learn in the PBL: (G.3) Geometric structure. The student applies logical reasoning to justify and prove mathematical statements. The student is expected to: (B) construct and justify statements about geometric figures and their properties. (G.9) Congruence and the geometry of size. The student analyzes properties and describes relationships in geometric figures. The student is expected to: (A) formulate and test conjectures about the properties of parallel and perpendicular lines based on explorations and concrete models. Key performance indicators students will develop in this PBL: Develop vocabulary (corresponding angles, distance from a point to a line, parallel lines, bisect, rhombus, angle bisector, conjecture, vertex), find patterns, create rules for bisecting angles, write and solve word problems 21st century skills that students will practice in this PBL: www.21stcenturyskills.org Critical thinking, problem solving, collaboration, communication STEM career connections and real world applications of content learned in this PBL:

Careers: Civil Engineering, Construction, Government/Political Science Connections: Roadway design impacts workers, land owners, design engineers, and city planners.

The Problem Your team has been selected by the Texas Department of Transportation (TxDOT) to plan two new county roads (CR131N and CR131S). Your first step is to create a drawing of the roads. The roads will cross the Bar-M Ranch and the ranch owner has some stipulations if he is to donate his land for this endeavor. The stipulations include: 1. When the roads enter his property, they must run east and west and be parallel. They are to be constructed so that they pass on the north and south sides of a square tract of land on the northwest corner of his ranch. The area of this tract is 225 acres. We will refer to this as “Tract A.” 2. There is a ranch road that starts at the northwest corner of the ranch and crosses the ranch at a 30o angle. He would like to keep this road intact and put stop lights at the intersections of that road and the two new roads. 3. For aesthetics, he would like to create another ranch road on the east side of Tract A that crosses the tract and intersects the southeast corner of the tract. This will create a piece of land that is in the shape of one of his favorite shapes as a kid – a diamond. Of course a math teacher of his called it a couple of other things and he’d like you to list all of the names for this shape on your report. He will fund and construct this road but for planning purposes draw it on your diagram. 4. You are to include in the diagram a line that bisects the angle formed by the original ranch road and CR131N (in the northwest corner) and a second line that bisects the angle formed by the ranch road and CR131S (the southwest corner of the diamond). These lines represent natural gas pipelines that the owner is currently in negotiations with a local gas company over regarding allowing these pipelines to cross his ranch. 5. When you draw the gas lines into your diagram you notice something interesting about the intersection of these gas lines. Elaborate about what you notice and make a conjecture about the intersection of these angle bisectors and angle bisectors in general. 6. Using a protractor measure the angles formed by the roads and the gas lines and put these measurements on the drawing. 7. When these two county roads exit Tract A (heading east) they are to diverge, symmetrically, so that when a person is 6 miles east of Tract A, they are 16 miles further away from the other road. Assuming the turn is immediate and the roads are straight, what angle will they have turned? How far would a person have to travel from the exit of Tract A to reach this spot? 8. When these two roads exit the tract of land (heading west) they are to converge at a 45 degree angle. The roads will continue until the roads are approximately 1 mile apart. At that time, they will turn westerly and be parallel again. What angle will this second turn to the west be? How far away from the tract of land will this turn be, and how far will a person have driven to reach this turn?

9. Finally, the rancher is debating putting a billboard advertisement up along the road. If a person is traveling on CR131N and hits the northwest corner of Tract A heading east at 50 miles an hour, how long will he be on the road before he is at the spot mentioned in #7 above? 10. A diagram showing Tract A, CR131N, CR131S, the gas lines, distances from any intersections, and any other point of reference must be created and formally presented to your boss.

5E Lesson Plan PBL Title: Acres of Fun TEKS/TAKS objectives: G.3B, G.9A Engage Activity Show the following video clip to your students: http://videos.cleveland.com/plaindealer/2008/04/orange_barrel_blues.html. After watching the video, have the students reflect in their journals regarding the following question: What types of math do you think are involved in the planning and creation of new roads? Introduce the students to the unit: Your team has been selected by the Texas Department of Transportation (TxDOT) to plan two new county roads (CR131N and CR131S).

Provide the students with an opportunity to complete a KWL chart regarding what they know about the challenge and what they will need to know in order to complete the challenge. Discuss with the students that they will need to solidify geometric content throughout the unit. They must first begin by researching how to bisect line segments and angles and creating a formal demonstration of that information for the class (see resource section below for sites to send students to). Upon completion of research, each group will present their demonstrations for the class.

Explore Activity Have the students work in their teams to complete the Explore Activity (see below). Upon completion of the Explore Activity, have the students investigate the size of an acre, hectare, and other measurements of land. Have the students create a poster with 3 land-based word problems that require the use of angle measurements, bisectors, and conversions to solve. Upon completion, proof the students’ problems and solutions and use a gallery walk format with the students sending them around to work all problems…including their own.

Upon the conclusion of all group presentations, have the students discuss observations, ideas, questions, and hypotheses with the rest of the class. Act as the facilitator, clear up any misunderstandings, and broaden the students’ vocabulary base. During the discussion, add to an existing word wall or have students add to their vocabulary journals. The students can then refer back to these during the project. Have the students reflect in their journal regarding the concepts and vocabulary that have been discussed during the Explain phase. Have the students apply their learning by individually creating a rough sketch of how to solve the problem in their journals. Upon completion, provide the students with time to re-assemble as a group and discuss the processes they feel will lead them to the final solution. © 2008 Transformation 2013

Time should be taken to expand concepts being discussed and mathematics being discovered. Provide the students with opportunities for practice of the concepts that they will be using to solve the challenge. Constructions required for this project will either be introduced or reviewed. Give the students time to practice their construction skills. Add additional constructions that may be related to topics that relate to those addressed in the Explore and Explain steps. Once the concepts are solidified, re-introduce the problem to the students and provide them with the opportunity to solve the problem and create a presentation of their results. Share the rubric with your students so they know the expectations for the project.
