Come and see
examples of how Web 2.0 and dynamic software
can transform math learning and teaching.
Participants will experience a series of
unique and compelling collaborative
activities that incorporate significant
software environments (spreadsheets,
Sketchpad and Web applets) that will help a
teacher to engage students in gaining a
deeper understanding of powerful
mathematical ideas.

| 4 | Measuring the
circumference of the Earth Over 2,000 years ago Eratosthenes made a remarkably accurate measurement of the earth's circumference. This project is a recreation of that measurement and requires collaboration of students in places at different latitudes on the earth to make shadow measurements, share data, use a spreadsheet (optional) to make comparisons, and then replicate and share their results. In the Spirit of Eratosthenes: Measuring the circumference of the earth - Ihor's article Starting this month - Collaborative Project Website GSP Model (Geometer's Sketchpad needed.) |
