Day I: Monday (June 2, 2003)

A. Introduction to InterMath

- Goals
- Components of workshop and continued professional development
- Components of InterMath website (Investigations, Dictionary, Discussion Board, etc.)
- InterMath Investigations Geometry Clusters for extra practice
- Examples of what previous participants have done
- Discuss online portfolio
- Discuss the components and structure of a write-up (including extensions).
B. Introduction to Technology

- Web Page Development
- Uploading process
- Dynamic Geometry Software
- Activities to reinforce Geometer's Sketch Pad skills
C. Introduce idea of representations

- Importance and role of representations in problem-solving
- Work through an investigation focused on real-world representations as a whole class using Geometer's Sketchpad
D. Discuss the components and structure of a write-up (including extensions)

E. Points, Lines, Planes, and Angles

Participants should choose investigations that involve:

- Identifying, describing and contrasting points, lines, line segments, planes, rays, and angles
- Describing and defining properties associated with points, lines, angles, and segments including distance, collinear, midpoint, congruent, bisector, interior/exterior, perpendicular, parallel, and intersecting
- Defining, estimating and measuring segments and angles

- Participants engage in investigations dealing with Points, Lines and Planes
F. Journal

A. Participants begin their first web-page write-ups to include in their online portfolios

B. Continued technological teaching and support (especially with GSP and the structure of a write-up)C. Continue to discuss the components and structure of a write-up (including extensions)

D. Journal
