I. Definitions

Web Data: Numerical information available on the World-Wide Web. Data may be available on a web page or as a file readable by a spreadsheet, a graphing calculator, or a statistical/numerical analysis software package.

Applet: A small, self-contained computer program that usually performs a task as part of larger software application. For example, most World Wide Web browsers are capable of using applets written in the Java programming language.

II. Representation Standard (NCTM):

Instructional programs from prekindergarten through grade 12 should enable all students to÷

á create and use representations to organize, record, and communicate mathematical ideas;

á select, apply, and translate among mathematical representations to solve problems;

á use representations to model and interpret physical, social, and mathematical phenomena.

III. Algebra Standard (NCTM):

Instructional programs from prekindergarten through grade 12 should enable all students to÷

¤ understand patterns, relations, and functions;

¤ represent and analyze mathematical situations and structures using algebraic symbols;

¤ use mathematical models to represent and understand quantitative relationships;

¤ analyze change in various contexts.
