Introduction Student Page Title Introduction Task Process Evaluation Conclusion Credits [ Teacher Page ] There are few ideas in life that will be useful forever. Concepts that change the way people view the world, change the way people approach challenges. Nowhere do more of these brilliant notions exist than in the field of mathematics. Today you will explore one of these ideas for the purpose of understanding it’s vast impact not just within the field of mathematics, but also within your everyday life. You will become historians, engineers and fortune tellers, and in the end it will be clear that one little thought can have a lasting impact on the world as you know it. In the following you will explore one of three concepts you know in math from three different angles. You will choose either the Pythagorean Theorem, The Quadratic Equation, or the number Pi and put together a presentation on where it came from/ the historical perspective, how its useful today/ the present perspective, and how it will continue to be useful/ the future perspective. Continue to the task page for details!

The Task Student Page Introduction Task Process Evaluation Conclusion Credits [ Teacher Page ] In groups of four you will construct a Power Point presentation to be given in front of the class on one of the three topics mentioned above. Your presentation will consist of : An introduction to your presentation telling us what it is on and what we can expect in your following slides. A main body that is broken down into four sections: Past, the history of your topic, who came up with it? When? What did people think of it at the time? What has it been used for in the past? Present, how is it applied today? Is it used in physics? Math? Engineering? Where can you find an application of it in your life? Future, use what you have learned to speculate on how people will use it in the future. Will it be the same as today? Will it become obsolete? Example, I want to see your topic in a worked example in a real world application. Don’t just give me a 2 + b 2 = c 2 , I want some thought into these. A conclusion summing up what you’ve told us, and what you learned from this project. Title

Conclusion Student Page Title Introduction Task Process Evaluation Conclusion Credits [ Teacher Page ] It is easy to get frustrated with math when all you see are numbers and symbols on a page in your text book. It is my hope that when you complete this lesson that you will see how fun math can be! Or at least that what you are learning has some real world applications. Everything here has a fantastic history and future and if you so choose you can be a part of that future, and possibly change the way people think about math, the world, or the universe!

Evaluation Teacher Script Conclusion

The Process (Teacher) [ Student Page ] Title Introduction Learners Standards Process Resources Credits Teacher Page In groups of four students will construct a Power Point presentation to be given in front of the class on one of the three topics mentioned above. The presentation will consist of : An introduction to the presentation telling what it is on and what we can expect in the following slides. A main body that is broken down into four sections: Past, the history of the topic, who came up with it? When? What did people think of it at the time? What has it been used for in the past? Present, how is it applied today? Is it used in physics? Math? Engineering? Where can students find an application of it in their life? Future, students use what they have learned to speculate on how people will use the topic in the future. Will it be the same as today? Will it become obsolete? Example, students will present their topic in a worked example in a real world application. A conclusion summing up the presentation, and what was learned from this project. See the student process page for a step by step. This lesson is intended to be comprehensive in nature accomplishing bits and pieces as the term progresses a minimum of three weeks assignment to presentation is recommended for completion. This lesson will require some outside of class work on the part of the students. It is recommended that groups are selected by the instructor to ensure quality and cohesive work. Elaboration may be required on some of the critical thinking aspects of the project, and should be tailored to the instructors desired goals for the project. It is recommended that computer lab time is set aside for this project at various stages of the term as the instructor sees fit. Evaluation Teacher Script Conclusion

Resources (Teacher) [ Student Page ] Title Introduction Learners Standards Process Resources Credits Teacher Page You will need: Access to a computer lab with internet connection Microsoft Office PowerPoint on as many computers as there are groups Computer with projector screen for presentations Access to YouTube A working knowledge of all of the above This lesson can be accomplished with one tech knowledgeable instructor Evaluation Teacher Script Conclusion

Evaluation (Teacher) [ Student Page ] Title Introduction Learners Standards Process Resources Credits Teacher Page The main objective of this lesson is to get student to make the connection between the lesson and their life. If it is clear that they have put some thought into this and were able to make that connection then this lesson was a successful one. Secondary objectives include use of web and technology, research skills, critical thinking skills, and speaking skills. If student display some or all of these the fore mentioned standards as well as the objective of the lesson will be met . See the rubric for detailed expectations. Evaluation Teacher Script Conclusion

Teacher Script (Teacher) [ Student Page ] Title Introduction Learners Standards Process Resources Credits Teacher Page Introduce the lesson: The student pages do a pretty good job with what is expected, but you may want to add some of your own thoughts or expectations here. Explain the functionality of the model. The side bar links will help students navigate between main heading pages, but there are also many links on the pages themselves that they will need to follow. Let them navigate their way through the task page where you may get some questions on expectations. This is primarily up to you to instruct them on what you want as the facilitator, you can also refer them to the Evaluation page, (link is in the sidebar,) for further details. The next step will take them to the process page where you can assign them to groups on step 1or have them navigate further to get the feel of the project before letting them start. Step 2 of the process page allows student to choose one of the three topic options. You can assign a topic or let them choose. I will navigate you through the Pythagorean Theorem option, The other two are typical. This link will lead them to step three of the process where they are instructed to divide up the work. I would leave this to them, but you may offer some guidance. The research topics for them to choose are listed see next slide . Evaluation Teacher Script Conclusion

Teacher Script Cont. [ Student Page ] Title Introduction Learners Standards Process Resources Credits Teacher Page . Each link will take them to their research topic page. These pages are embedded with web links related to there topic and research interest. There is also instructions on what is expected. It is recommended that you navigate these pages so that you are familiar with them. The following is an example of the Past page. And one of the web link pages. See the next slide for continued script Evaluation Teacher Script Conclusion

Teacher Script (Teacher) [ Student Page ] Title Introduction Learners Standards Process Resources Credits Teacher Page . Evaluation Teacher Script Conclusion Also On the process page the students are instructed they would be grading each other. This is one method for tracking participation. It is recommended that you develop a way of tracking participation tailored to your expectations and classroom. Step 5 of the process pages has web links to YouTube demos on Microsoft PowerPoint that may be applicable to their presentations. The final steps outline expectations of the presentation. At this point you should direct them to the Evaluation pages and review the expectations.

Conclusion (Teacher) [ Student Page ] Title Introduction Learners Standards Process Resources Credits Teacher Page There are few ideas in life that will be useful forever. Concepts that change the way people view the world, change the way people approach challenges. It is the purpose of educators to enlighten young minds and guide them to become the ones that to come up with these notions. Use this lesson to help you on your quest.
