Algebraic Problem-Solving Using Spreadsheets: This is a unit for grade 9 students that emphasizes moving from numerical to symbolic representation.

Algebra Problems: This site offers a collection of simple story problems illustrating concept-based problem solving. These are typical of problems in high school textbooks and in a variety of competency tests. In some cases, the "answer book" solutions are included.

Ask Dr. Math: This site features algebra questions and answers for high school students.

Fun with Calendars: This activity uses a fun mathematical puzzle to demonstrate solving a simple linear equation. It's an average math trick, but it's an excellent activity to demonstrate algebraic applications.

Graphing Lines and Curves: The University of North Carolina provides these interactive Java Applets to help students better understand graphing.

Graphing Lines and Curves: The University of North Carolina provides these 17 videos and animations dealing with slope, parabolas, absolute value, graphing, functions, and more.

Interactive Algebra: This site features a total of 14 tutorials on three different topics: equations and inequalities, factoring, and graphing.

Interactive Algebra: This basic algebra tutorial designed by and for high school students includes Algebra Postulates (things you can do with equations and inequalities), Function Basics and Simple Graphing, Kinds of functions (periodic, odd, even, etc.), and Function Squashing.

Internet Center for Mathematics Problems: This site tries to list all sources of mathematics problems on the Internet, along with related information.

Introduction to Algebra: Here you'll find clearly-written definitions and easy-to-understand algebra examples.

Introduction to Vectors: This is an excellent and exhaustive tutorial on vectors.

The Linear Algebra Toolkit: This site is designed by staff at Old Dominion University to help a student understand basic linear algebra procedures. Learn to solve linear systems of equations or transform a matrix to row echelon form.

Mathematics with Alice: Teachers, let Lewis Carroll's Alice in Wonderland teach your students about algebra. Students can work independently in the classroom or home posting and solving algebra problems on the Problematic Board.

Math Forum: K-12 Algebra Resources: This site includes Classroom Materials for Teachers and Students, Software for Algebra, Internet Projects, and Public Forums for Discussing Algebra

Math Lessons by Cynthia Lanius: Cynthia Lanius is a mathematics teacher, currently working at Rice University in Education and Outreach. Her "Math Lessons" site offers lessons in algebra, exponential growth, the mathematics of cartography, geometry, and polynomials.

Math Power: Basic math skills are explained very clearly in student tutorials, where students explain step-by-step how to solve unequal equations, algebra word problems, and factoring polynomials. Homework assignments are available, as are study and test-taking tips. Professor Freedman's video
snippets explain some basic concepts such as additions and subtraction of signed numbers.

Math Share Shop: Check out the SMART page for a list of math topics, then explore the subject you want to learn more about.

Mudd Math Fun Facts: Written by a professor at Harvard, these challenging problems and brainteasers are sure to generate renewed interest and cause your students to look at math in a whole new light. Use them to kick off each class period, then challenge your kids to create new fun facts of their own.

Pi Mathematics: Pi Mathematics, a collaborative project, using the concept of Pi as the focus, is a multidisciplinary project which includes math, history, English, and thinking skills and is designed for fifth through eighth graders. It allows students to discover the approximate value of P using measurement and reporting the data, applying formulas, problem solving, and participating in a collaborative project utilizing Internet resources. Students will also explore the history of Pi using Internet references.
Review Topics: These are lecture notes, definitions, and examples from an algebra class. They include integer exponents, scientific notation, addition and subtraction of polynomials, multiplication of polynomials, division of polynomials, factoring, rational expressions, complex fractions, distance/midpoint, solving systems of equations with two variables, and solving systems of equations with three variables.

Solving Quadratic Equations: This lesson has the students solve quadratic equations by factoring, solve quadratic equations by completing the square, solve quadratic equations by using the quadratic formula, and solve quadratic equations by graphing.

S. O. S. Mathematics: Algebra: This site offers tutorials, sample quizzes, worksheets, and interactive lessons on common algebra topics, including quadratic equations, fractions, conversions, solving equations, polynomials, and much more.

U. S. Shirts Problem in Algebra: The U.S. Shirts Problem is a sample three-day lesson module. Teachers are encouraged to read over the problem situation at the beginning of the period and then give the students time to work in cooperative groups to solve the problem. Groups are given overlays to describe the problem and asked to present their results to the rest of the class.

Visualizations in Algebra: This workshop focuses on ways to enhance students' powers of visualization and their ability to make connections in Algebra I and II. The TI-81 Graphing Calculator is introduced and its use in any high school mathematics course is emphasized.

Word Problems in Algebra: This site includes a collection of simple word problems illustrating concept-based problem solving. These are typical of problems in textbooks and in a variety of competency tests. In some cases, the "answer book" solutions are included.

Zona Land: Created by high school math and physics teacher Ed Zobel, Zona Land provides resources for students to fully grasp major concepts in Algebra, Geometry, and Physics. Using Java programming, Ray Tracing and VRML (a virtual reality language), he creates tools and lessons. Divided into two sections, "More Mathematics than Science" and "More Science than Mathematics," students can better visualize waves, graphing, and much more.
