My third page has additional resources and my lesson plan. My first page has my article abstracts.

Web 2.0 Tool [|Geogebra]

Geogebra is a free online website. It did not even require the students to create an account or log on. I liked Geogebra because it is a great way for students to visualize mathematical concepts. It allows students to sketch points, shapes, and lines. The site has a graphing feature that allows students to graph equations. Teachers can also create tools and send them to their students to make the lesson go more smoothly. I think it is an important resource because math has many different things that need graphing.

To use Geogebra for my Pythagorean Theorem lesson I would have students create a right triangle. To do this they will first create two points, and then create a line segment connecting the points. Then they will go up to the tools and create a perpendicular line. Next the students will create a point on the perpendicular line. The students will connect the three points, creating a right triangle. Now students will go up to the tools and measure each side of the triangle. Next the students will go to the “View” menu and go down to cas, which is a calculator. Then the students will type in (distance A)^2 + (distance B)^2. Then have them square root it to show it equals the hypotenuse. This can be done by ((distance A)^2 + (distance B)^2)^(1/2). Finally, the students can manipulate the triangle and see that the Pythagorean Theorem works for all right triangles. Below is how I would want the end product to appear.
