Web Weaver September 2010: Mathematical Proficiency
A collection of historical and contemporary resources about mathematical proficiency as well as an exploration of two Google search enhancements - Wonder Wheel and Timeline. This article will appear in the September issue of the Wisconsin Mathematics Council Newsletter.

Web Weaver Winter 2010: Exploring Mathematical Connections
How Stuff Works- Spider Web An excellent step-by-step applet that reveals the geometric beautiful of the web. The connections in the orb spider’s web are easy to see and appreciate; I hope this column will help you make equally strong connections on the WWWeb to help your students weave mathematics into their lives.

The Middle School Portal offers both strong standards-based resources and a chance to connect with colleagues through the MSP2 social network.
  • Connections! Math History as a Teaching and Learning Tool features resources that highlight the development of mathematics over time and in diverse cultures. Each resource corresponds to a topic usually covered in the middle grades curriculum, such as measurement, geometry, or probability, and connects it to its historical context.
  • Connections! Linking Mathematics offers resources that connect mathematics to social studies, art and science. With lesson plans, problems to solve, and examples of mathematics at work in unusual contexts, the site makes plain the idea that mathematics permeates life.
When an earthquake in Illinois rattles the house like a passing snowplow, you felt it! If you did, you might be one of the over 1800 people who reported the quake to the USGS. You can see maps and a summary of the reports by zip code for the February 10th M3.8 quake centered on Virgil Lake, Illinois .
The USGS Real-time World Map displays ongoing information about earthquakes within the past 7 days accompanied by an ingenious key that reveals patterns in the data through both the size and color of the square marker.
Landmarks_for_Schools.pngLandmarks for Schools is a phenomenal collection of data sources and teacher tools from author and educator David Warlick. Part of a collection that receives over a half-million hits a day, this link to the Raw Data section will open hundreds of possibilities for exploration from Baseball Statistics to World Values.
  • A quick thought-provoking connection, the Pew Research Center’s Daily Number is a great resource for a writing warm-up topic or exit slip for middle or high school students.
  • For a more comprehensive dip into data, Key Data Trends explores the mood of the country based on the Pew Research Company’s recent survey questions on such topics as Internet Penetration and Presidential Approval ratings.

The Center for Innovation in Engineering and Science Education (CIESE)
CIESE focuses on collaborative and real time data projects that connect students to others throughout the world. Engaging, well-articulated projects such as Bucket Buddies and Square of Life for younger students to Biodynamic Farming and Human Genetics for students in grades 6-12, make sense of the world in which we live while integrating writing, science, mathematics and geography. Each project has links to National Science and Mathematics standards and is almost guaranteed to produce a memorable experience.

  • On a softer note, the last few sites invite you to “purl up” and experience the connection between decorative arts and the world of mathematics. Begin by visiting the Home of Mathematical Knitting , but don’t let this bare-bones list of links fool you, it’s home to some of the most amazing topological knitting articles, patterns, and pictures including patterns for Möbius strips and Klein bottles.
  • For more experienced craftspeople, this Möbius Scarf Pattern is a delicate and artful rendition of the never-ending strip that is sure to please your favorite fiber geek.

TED Talks: Margaret Wertheim on the beautiful math of coral
Celebrating the esthetic and poetic dimensions of science and mathematics modeling hyperbolic geometry by crocheting a coral reef, Wertheim fairly vibrates with intellectual energy that connects the traditional decorative art of crochet with environmental activism and the history of mathematical thought. Among other amazing feats, she presents a wooly proof that Euclid’s Parallel Postulate is wrong! Be prepared to watch this more than once and to share it with your favorite art teacher. Viva connections!
