## Workshop 24

**Thursday, May 7: 3:45 PM – 4:45 PM**

*Workshop Description:* GeoGebra – Redefining Math Instruction and Learning

GeoGebra is a dynamic tool for both teaching and learning mathematics. This workshop will demonstrate how using this software tool can raise student interest, increase depth of understanding, make connections among areas of math study, and improve students’ abilities to think mathematically. This session will focus on Algebra II, Precalculus and Calculus. GeoGebra is a free, multi-platform software tool that allows the exploration of mathematical ideas using either algebra-based or geometry-based strategies. Teachers can use GeoGebra to create graphic illlustrations, dynamic classroom presentations, and even videos. Students can use GeoGebra to learn mathematical concepts through both guided discovery and free exploration. Using examples from algebra, geometry, and calculus this session will demonstrate how GeoGebra can be used to redefine learning whether a single computer is being used or each student has his or her own. Basic uses are easy to learn, and more sophisticated activities can be added as user familiarity increases.

*Workshop Presenter:* David Bowie

David Bowie is a semi-retired math teacher at Lewiston High School where he teaches AP Statistics and supports teachers in using technology in all content areas. He has presented inservice courses in computer technology for many years in Lewiston, and is now working with MLTI to provide technology training for mathematics teachers.
