TI-84 CABRI JR. GEOMETRY WORKSHOP FOR HIGH SCHOOL TEACHERS

 Welcome to the winter 2012 multimedia geometry workshop for high school mathematics teachers. In this five-hour workshop, the concentration will be on the Cabri Jr. geometry software program that is embedded in Texas instrument’s TI-84 Plus graphing calculator. As you experience this multimedia mathematics workshop I hope you will be able to grasp, not only the concepts of geometry, which you already know, but that the multimedia aspect of the presentation will enlighten you to the modern movement of mathematics with technology, especially geometry.

At the completion of this workshop, you will be expected to:

1) experience the use of Cabri Jr to draw geometric shapes and solve geometric problems 2) use the graphing calculator as a geometric tool for teaching in your classroom 3) use other multimedia technology to enhance the leaning of geometry.

This workshop was planned because many geometry teachers do not use technology, and in particular, graphing calculator technology in their classrooms. The incorporation of graphing technology into geometry lessons to enrich instruction and extend students' understanding of geometry. Topics essential to geometry, such as: Intersecting lines; angles and transversals; transformational geometry (translation, reflection, rotation, and dilation); polygons (example, triangles and quadrilaterals) ; area relationships, and circle theorem (chords, secants, and tangents); and the circle itself, can be addressed using the Cabri Jr on the TI-84 Plus.
