2. Are you feeling sorry for yourself? What if your problems were reasons to rejoice? Can you imagine that a crisis might be an opportunity or even a gift in disguise? Does this sound like a student in Kathy Craven’s class the night before a project is due? Well it’s also one of the lessons Jason Stevens learns in The Ultimate Gift, an inspirational film and novel by Jim Stovall. The imaginary character Red Stevens teaches his great-nephew, "In the end, a person is only known by the impact he or she has on others.” (Nuzzo, 2008)

3. One of the 12 gifts is the “Gift of Learning”… Kathy Craven has impacted my life and my students’ lives by introducing me to tremendous resources and fantastic projects in a very short amount of time. One thing, that I learned is to use film for introduction of course content and student projects.

6. Introduction Student Page [Teacher Page] The Pythagorean Theorem was one of the earliest theorems known to ancient civilizations. This famous theorem is named for the Greek mathematician and philosopher, Pythagoras. Pythagoras founded the Pythagorean School of Mathematics in Cortona, a Greek seaport in Southern Italy. He is credited with many contributions to mathematics although some of them may have actually been the work of his students. The Pythagorean Theorem is Pythagoras' most famous mathematical contribution. According to legend, Pythagoras was so happy when he discovered the theorem that he offered a sacrifice of oxen. Pythagoras needs your help in showing disbelievers that his theorem works for all right triangles. He has the problem that some people do not believe him because they do not understand how he explains it. Your job as a group is to find ways to make everyone believers and show them that the theorem exists in real world examples. Be prepared to work hard on this project. The people you need to convince are stuck in their ways and not easily swayed. Title Introduction Task Process Evaluation Conclusion Credits

7. The Task Student Page [Teacher Page] • You will be traveling all the way back to ancient times in Greece to work as a team studying under the great Pythagoras. But be careful, the Pythagoreans had many rituals, and they approached mathematics with an almost religious intensity. Their power and influence became so strong that some people feared that they threatened the local political structure, so they were forced to disband. However, many Pythagoreans continued to meet in secret and to teach Pythagoras’s ideas. This will be your quest, and during it you will be able to: • build a table of values showing the relation between the sides of a right triangle • apply the Pythagorean Theorem to any triangle • discover the Pythagorean Theorem • show that the Pythagorean Theorem holds true for small right triangles • show that the Pythagorean Theorem does not hold true for any triangle that is not a right triangle • show to the disbelievers that the Pythagorean Theorem works • apply the Pythagorean Theorem to modern, real world problems • Once you return from your journey, you will use Xcel to build a table that you can present to any disbeliever to show them the pattern and relationship between the sides of a right triangle. You will put together a PowerPoint presentation that includes you table and different triangles, and the solutions to two real world problems that use the Pythagorean Theorem. Remember, you have to show that the Pythagorean Theorem works only for right triangles, not all triangles. Title Introduction Task Process Evaluation Conclusion Credits

8. The Process Student Page [Teacher Page] We’ve traveled way back to the time of Pythagoras. In your assigned group, you will navigate your way to proving the Pythagorean Theorem and building a table of values that will show the pattern of the relationship between the sides of a right triangle. When you get back, your last step will be to put together a presentation including real world examples of how to solve them. Meet your fellow travelers. You will be learning together and helping one another understand the Pythagorean Theorem. Open up a good line of communication. Gather some background information on where you are going and learn a little more about Pythagoras. Start by discovering the proof of the Pythagorean Theorem. Is this method any different? What does it say about the triangles it applies to? How can you write down this proof so that anyone can understand it? (Actually write it down, you need it for later) Build a table of values for the lengths of the sides of a right triangle. Write all different lengths, but keep it simple. It will be easier to see the pattern if you use small numbers. Here are some columns you might consider having in your table: length of side 1, square of side 1, length of side 2, square of side 2, length of hypotenuse, and square of hypotenuse. How does this apply to real world problems?? Check it out, here are some good problems to solve. Put this all together in one presentation. Make sure to use Xcel to build your table of values. Make this presentation look professional, you may need to use it at any time. Title Introduction Task Process Evaluation Conclusion Credits

10. Conclusion Student Page [Teacher Page] GOOD JOB!!! You have successfully convinced the disbelievers of the Pythagorean Theorem that is does in fact hold true for right triangles. Now you can begin to apply the theorem to right triangles in mathematics and in life. Because of your great work on the journey, Pythagoras can once again get back to the study of mathematics instead of having to worry about proving to everyone that his theorem holds true. You have done a great service to Pythagoras and all his students and colleagues. Your journey may be over, but you now have a presentation you can give to anyone in modern times that does not believe in the Pythagorean Theorem.

13. Introduction (Teacher) [Student Page] Teacher Page Title Introduction Learners This lesson stems from the book, Looking for Pythagoras used by Poudre School District in Fort Collins, Colorado. It has been designed to make the lesson more interactive and for students to use experimental techniques in their learning. Some students may need additional help and resources from the teacher, and that is perfectly fine. Other students may begin to want to learn everything using a WebQuest. While participating in this WebQwest, students will learn background information on Pythagoras and ancient times in mathematics, along with how to prove the Pythagorean Theorem and apply it to modern problem solving.

16. The Process (Teacher) [Student Page] Teacher Page Students must be split up into groups of four before the activity begins. Be aware of how they work together and the individual strengths and weaknesses of the students in the group. They will need to work very closely with each other, so make sure they will get along for the remained of the project. Multiple classes may be doing this at one time, so use each one as a learning experience. We’ve traveled way back to the time of Pythagoras. In your assigned group, you will navigate your way to proving the Pythagorean Theorem and building a table of values that will show the pattern of the relationship between the sides of a right triangle.
