Problem-Solving Lessons for Understanding Average
Middle School (5--8) Workshop (Admission by Ticket)

In recent years, the teaching of average has undergone a radical rethinking. We now use concrete and visual methods of teaching for better conceptual understanding and to form a more meaningful basis for learning procedures. My presentation shares several problem-solving, 
hands-on activities used with sixth graders that provide visual and exploratory experiences for understanding average. Lessons include a spreadsheet (available to participants) that leads students through an increasingly more sophisticated understanding of the mean. Additionally, time will be made available to discuss recent research on the teaching of average and teaching ideas found in recent literature.

Session 164 - (Thursday) Macintosh Lab (Moscone 110)
Fractal Geometry and the Internet
High School (7--12) Workshop (Admission by Ticket)

This workshop will be in two parts.  Part I will be a hands-on, activity centered introduction to the world of fractal geometry.  Part II will be an opportunity for further explorations in fractal geometry by using the Internet to explore fractal sites.  Many of these sites are simultaneously beautiful and educational.

This session will demonstrate three innovative computer programs used to explore mathematical topics such as fractions, probability, statistics, graphing, and fractal geometry. All three programs provide tools for the user to control in order to promote an open-ended learning environment. 
Participants will be actively engaged in exploring and conjecturing about mathematics with these exciting teaching and learning tools. The programs will be made available free to the participants.
 

These programs were created by members of the mathematics education group at the Curry Center for Technology and Teacher Education and will be made available free to the participants.

Jen and Kelly's Excellent Adventures with Technology: Check out Our Favorites in software and CD ROMs
Elementary (K--6) Workshop (Admission by Ticket)

Come experience the excitement of using meaningful computer technology in the mathematics classroom! Participants will learn how to embed computer technology into the elementary school mathematics curriculum. These hands-on experiences will demonstrate how computer technology can be used to meet curricular objectives and NCTM Standards. Participants will view a wide selection of mathematics software and CD ROMs that can be used to enhance, extend, and excite mathematics learning at the elementary school level!

Raising students' achievement is the primary goal of this joint interprovincial partnership project with ITP Nelson Canada to develop exemplary curriculum-based instructional resources for teaching and learning mathematics in western Canada. A U.S. version of algebra 1is now available. Participants will be invited to use and explore The Learning Equation Mathematics (TLE Math) CD-ROM learning resources in a computer-lab environment. The results of student-achievement studies, effective instructional strategies, and changing roles for students and teachers will be discussed. Samples of students' writing and feedback will be available. The participants will receive a complimentary CD and User's Guide Sampler for The Math programs.

Using Technology to Explore Mathematical Patterns in African American Hairstyles
Middle School (6--8) Workshop (Admission by Ticket)

 Computer simulations of patterns used in hair braiding and weaving traditions in African American communities will be demonstrated as a way to explore mathematical ideas. These ideas range from elementary shapes and number structures to logrithmic spirals and fractal designs. The ethnomathematical foundations of the talk have profound implications for school to work and multicultural issues, instructional organization, professional development, the use of technology as a tool and improving school/community relations.

The Global Gardening Project combined geometry and biology to allow students greater understanding of both subjects. Through the use of active learning strategies, involvement in the National Monarch Watch, and the design and creation of an actual butterfly garden , these 
students became active and eager participants in the instructional process. This workshop will overview the project and engage participants in active learning strategies they can utilize in any mathematics classroom.
