Is it true for any triangle that the sum of its angles will add up to 180 degrees? Why does the area formula for a trapezoid work? These types of questions are some examples of the many geometrical mysteries students will be able to solve through the use of Geometer's Sketchpad (GSP). GSP is a dynamic visualization tool that will help my students develop a deeper understanding of geometry.
I find that my students have a great deal of difficulty with basic geometric concepts. I do my best to use hands-on manipulatives to help them "see" what is happening; yet, the use of manipulatives can become cumbersome at times. For example, to prove that all angles of a triangle - no matter the shape or size - will equal 180 degrees, I have students cutting out various triangles from paper, clipping off the corners and placing them to show they form a straight line. This entire process is effective yet extremely messy and time-consuming. GSP will offer the efficiency of technology and, as a result, will allow the students to focus more on what is happening mathematically than worrying about how quickly they can clean up the classroom. Additionally, I find that GSP is extremely student-friendly, which helps my students overcome their initial anxiety towards mathematics. With a simple drag of the mouse, students will be able to construct and explore an object's mathematical properties.
I am currently teaching 5 sections of Geometry in South Central Los Angeles at Locke High School. My school has invested in purchasing the GSP software for one of the technology computer lab. However, I would love to demo concepts for my students using Geometer's Sketchpad in my classroom. Demo abstract theorems and axioms in class will allow students to have a visual and tangible image of the concept at hand.
Activities that I would like to demo in class with Sketchpad include, 1) exploring the relationship between parallel lines and angles and parallel lines and proportional segments, 2) exploring the relationships in circles between arcs and angles, and 3) developing the formulas for the areas of quadrilaterals.
Secondly, I am excited by the sheer amount of innovative multimedia available with my new geometry textbooks. I am currently working on integrating powerpoint presentations for warm ups and checks for understandings into my lessons. I would love to be able to have a working computer to show my students these problems. In addition, it will allow me to create innovation lessons that meet California's Mathematics Standards in an interactive and visual manner by utilizing the software that came with my new textbooks. Having a teacher computer will enable me to cut down on paper usage because I will be able display custom made quizzes and problems from the publisher's website.
Lastly, having a teacher laptop will enable me to more organized and efficient. A teacher computer will allow me to hand out up-to-date progress reports biweekly because I will be able to use a computer based grading program. I can create power presentations and integrate software assessments that came with my new Geometry textbooks. Lastly, I can be a more effective teacher because I will have a portable and reliable computer which I can use for creating lesson plans and rubrics no matter where I am in my school.
