This site was started by the Think Quest program, so students just like you created it and maintain it. That doesn't mean that the website is any less fantastic than if a group of teachers had put it together. The site offers a wealth of mathematics help. On the left side of the page, you'll find the "Learn" column. This portion is helpful for brushing up on concepts you may not have gotten the first time around in school. On the right side of the page, you'll find an "Interact" column, which is where you'll find the message boards to ask questions, lists of formulas, quizzes and a stellar math links. More »

This website was designed by math teachers: The National Council of Teachers of Mathematics. Do not be fooled into thinking that it'll be a horrible learning experience, though. These teachers knew what they were doing. Amazing, huh? Sometimes teachers really do understand how to help students. On this website, you can choose whether to study by types of challenges or math concepts. Here's what you do:

- Select a challenge or math concept.
- Attempt to answer the problem presented on your own.
- If you're stuck, go to "Getting Started" to give you hints on where to begin solving or click on the "Hint" to give you a clue.
- Click on "Answer" to check your work.

The challenges range from linear equations and functions to probability and statistics with geometry and measurement in between. More »

This website is a kinesthetic learner's dream come true. It's difficult for high school students who need to experience, sense and move to get tough mathematical concepts into their heads sometimes, especially in a setting that might not meet their learning needs. Are you one of those students? These virtual manipulatives can help! They offer explanations of math concepts in a hands-on way. You can drag beads on the online abacus, solve interesting puzzles by moving around the components and create graphs, patterns and mazes to analyze and explore data. The manipulatives allow you to see exactly what the math means behind the equation, which is oh-so-helpful when you're stuck. More »

If it's your junior or senior year and you've been assigned the thrilling task of coming up with a math-based research project, but you are at a complete loss about how to even start, then take a peek at the website above. On the website, which is really just a list of ideas, you'll find a wealth of high school math project ideas suitable for a math-based science fair project or senior project. Here are a couple:

**Mazes:***Is there an algorithm for getting out of 2-dimensional mazes? What about 3-dimensional? Look at the history of mazes. How would you go about finding someone who is lost in a maze (2 or 3 dimensional) and wandering randomly? How many people would you need to find him or her?***Kaleidoscopes:***Construct a kaleidoscope. Investigate its history and the mathematics of symmetry.***The Art Gallery problem:***What is the least number of guards required to watch over all paintings in an art gallery? The guards are positioned at specific locations and collectively must have a direct line of sight to every point on the walls.*
