July - September 1999

Back to What's New

## September

- Submissions to the Math Forum's Problems of the Week (30 September 1999)
- The Forum's six problems of the week (Elementary, Middle School, Geometry, Algebra, Calculus/Trigonometry, and Discrete Math) received more than 9,530 submissions during the month of September. Since problem submissions receive responses, sometimes more than one, that's a lot of work for some very busy mentors!

- Additions to the Math Forum's Internet Mathematics Library (30 September 1999)
- Over 60 entries were added or updated during September of 1999.

- September additions to the Dr. Math Archives (30 September 1999)
- More than 125 new question-&-answer entries were added to the tables of contents during September of 1999.

- New Dr. Math FAQ (19 September 1999)
- How do you round a number to the nearest tenth (10th), hundredth (100th), thousandth (1000th), etc.? See Dr. Math's Rounding Numbers.

- Math Forum Problems of the Week (POWs) (6 September 1999)
- After a summer hiatus, the Math Forum's Problems of the Week, designed to provide creative, non-routine challenges for students in grades 3-12, have resumed for the 1999-2000 school year. This year we will be hosting six problems: Elementary, Middle School, Geometry, Algebra, Discrete Math, and Trig & Calculus. Please consider joining our volunteer cavalry mentor group, whose members send replies to a few students each week. For more information, choose a level or topic and follow its Mentor Project link; to read about how students can participate, follow the link to a Current Problem, then select Information and Guidelines, or Rules, or Frequently Asked Questions.

## July-August

- Additions to the Math Forum's Internet Mathematics Library (31 August 1999)
- Over 600 entries were added or updated during July and August of 1999.

- July-August additions to the Dr. Math Archives (31 August 1999)
- More than 160 new question-&-answer entries were added to the tables of contents during July and August of 1999.
Forum participation in institutes and workshops, summer 1999 (July-August 1999)

- Chichester High School, Chichester, PA

Math teachers from Chichester High School took an in-depth tour of Math Forum services, such as the Problems of the Week; and documented some of their own discoveries and interests, including how to find sets of data on the web, and how to download and import them directly into a spreadsheet program.

- DREI 1999 - DIMACS Research and Education Institute

Graph Theory and Its Applications to Problems of Society; (Mathematics and the Internet). Teams of classroom teachers and mathematics researchers are collaborating in developing classroom materials, professional plans, and activities, and are working with software relevant to discrete mathematics.

- Geonet Summer Program - Emerson High School, Union City, NJ

A summer program designed to teach middle-schoolers about geometry and its applications. Teachers and high school interns were trained in the use of technology in the math classroom, in particular the Geometer's Sketchpad, and a curriculum was written for the four-week program. Math Forum staff provided ongoing support through classroom visits and email.

- ESCOT Integration Team workshop - Swarthmore, PA

A dozen teacher/educators and another dozen developers/researchers attended, learning about Sketchpad, AgentSheets, SimCalc, ESCOT, and middle school math curricula, and prototyping some component-enhanced problems of the week.

- Park City Mathematics Institute - Park City, Utah

Math Forum staff worked with the High School Teacher Program for the fifth year, teaching the teachers about the possibilities of using the Internet in the classroom and providing small group instruction in Web page writing and JavaSketchpad.

- Weaving Research and Practice (WRAP)

Bridging Research and Practice (BRAP) is a research project designed to answer the question: How can multimedia articles make effective contributions to professional development and research in mathematics education? In August, seven teachers returned to the Forum for a second institute, exploring the writing of a multimedia article about discourse in the mathematics classroom.

- West Morris Regional High School District, West Morris, NJ

High school teachers explored mathematics and the Internet, learning ways to incorporate the Internet into their math curricula.

Forum participation in meetings and conferences, Summer 1999 (July-August 1999)

- Cubic and quartic equations (4 August 1999)
- Robert L. "Dr. Rob" Ward has added a discussion of quartic equations to the Dr. Math FAQ.

- Conference on Technology and NCTM Standards 2000, hosted by the Electronic Format Group and the Eisenhower National Clearinghouse, a followup to last year's conference when Forum perspectives on technology were presented. This year's conference was smaller and the technologists worked with Standards writers to develop electronic examples for the Standards.

- Math Metadata, an informal group working to pull together a structure and strategy for developing metadata for the entire math and math education community. Representatives from IMS Metadata, the Eisenhower National Clearinghouse, Engineering Project Needs, and other organizations attended the meeting, and members from AMS, MAA, NCTM, etc. will soon be added.

- NCTM Electronic Resources Committee, a meeting at which recommendations regarding technology were drawn up for the NCTM board.

- NCTM Toyota TIME: 1998 Toyota TIME Grant Recipients met to share their projects. Math Forum staff presented ways the participants could add a Web component to a project or use the Web to disseminate information about projects.
