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 | The Weird
Number The story of the Weird Number is a delightful excursion into a fantasy world of a town inhabited by natural numbers. A robbery occurs that helps them to learn they are rational numbers. But nobody could believe that there were strange numbers living in the dark woods that weren’t rational. http://dynamicmathclassroom.blogspot.com/2014_10_01_archive.html |

| 5 | A Pi Day
Mystery My favorite Pi Day activity is the one where random needles dropped on parallel lines lead to an approximation of Pi. Why Pi? Good question. We'll answer that in this story. George Reese's explanation. |

| 7 | Measuring the
circumference of the Earth Project 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.
