DE Lesson(s)

Please see the address below for my Lesson.  Each student will have appropriate access to my Wiki.  Also through this Wiki students will encounter real-world photos of triangles, an Audacity file, YouTube videos, and other resources that will be important to mastering the Standard.

In this there are several lessons as this Wiki contains half of one unit in Math 2.  There is a pre- and post-assessment, notes, practice questions, discussion posts, and learning tasks.  I feel that if students utilize all parts they will be able to perform any problem on the EOCT for Special Right Triangles.

 

Please let me know if you need access to the site.  I will need your email address.

 

Enjoy!

DE Lesson Plan

Web 2.0 Lesson Template

1. Title:   Special Right Triangles: 30º - 60º - 90º and 45º - 45º - 90º

2. Grade Level/Subject:   Mathematics II – 10^th Grade Level

3. Prerequisite Knowledge:   Students must be able to identify a triangle.  Students must know how many degrees the three interior angles of a triangle add to be.  Students must recognize right angles and be able to relate them to triangles.  Students must be familiar with the Pythagorean Theorem.  Students must know the difference between complementary angles and supplementary angles.

4. Approximate time for the entire lesson:  This site contains one-half of the standards for 10^th grade students in Trigonometry.  There are several lesson concepts within this standard.  For my support classes, this module should take five 90-minute blocks.

5. Learning Objectives:   Students will be able to recognize and solve the two special right triangles according to their appropriate side ratios.  The students will be able to find the third side of a right triangle given two sides.  The students will be able to fully describe why these two triangles special and tell why other triangles are not.

6. Relevant Standards:
MM2G1. Students will identify and use special right triangles.

      a. Determine the lengths of sides of 30°-60°-90° triangles.

      b. Determine the lengths of sides of 45°-45°-90° triangles.

7. The Web 2.0 tool chosen to deliver the lesson:  Wiki, Flickr, YouTube, and Audacity will be utilized in these lessons.

8. Assessment to measure learning outcomes using this lesson:   The assessment will be graded right or wrong as this is the only way to ensure full mastery of the standards.  It will consist of six short answer questions in which mathematical computation will be utilized.  These six questions were picked as a pre and post assessment to evaluate what the students learned.  As will be explained to the students, a passing grade on the post assessment indicates mastery of the standard.

Web 2.0 Technologies

(1) What is 2.0? (2) Describe your initial thoughts about integrating Web 2.0 technologies into your teaching.

            When I first began working through this class I was not aware of the many facets of the Internet.  I knew how to access it and that everything was available at the drop of a hat.  Just as I have found that I do not fully understand the history of math, I have now realized that I do not understand the history of the World Wide Web.  I have taken for granted many things that I have been given and without that knowledge I feel that I cannot reach my fullest potential. 

            With that being said I really had to do some research to really understand where Web 2.0 technologies came from.  What I found was a plethora of information that I in a way already knew, but did not know the buzzwords that went with it.  Simply I found that Web 1.0 was the start of the World Wide Web that was executively led.  Then came Web 2.0 which allowed users to create their own personalized sites and gave way to networking.  I found this journal article that described Web 2.0 technologies.
            Web 2.0 technologies encompass a variety of different meanings that include an    increased emphasis on user generated content, data and content sharing, collaborative   effort, new ways of interacting with Web-based applications, and the use of the Web as a social platform for generating, repositioning and consuming content. "Web 2.0" refers to a perceived second generation of Web development and design that facilitates communications and secures information sharing, interoperability, and collaboration on the World Wide Web. (Harris & Rea, 2009, p. 137)
            There are several innovations that have come with Web 2.0 technologies such as Facebook, wikis, YouTube, blogs, virtual video games, all things Google, Skype, etc.  I could go on for lines and lines of examples however I think these pertain to major categories such as allow people to become more social over thousands of miles and allow businesses to network through different countries.  Through Web 2.0 the possibilities have become endless as the Web is more effective and efficient for all users.
            I feel that integrating Web 2.0 technologies in teaching is essential to stay current with the 21st century.  I do believe that it would not be as easy as it should have been if it were not for this class.  I thought myself to be computer savvy, but only until now did I realize that there were so many free programs at the touch of a hand.  I still think of these as things that I would need to purchase in order to make it effective to my students.  Now, however, I can take Audacity and Movie Maker to create more tools for my students to be successful.  These resources will also be widely available to parents as high school math takes on a deeper level today than it did 10 to 15 years ago.
