- Ask Dr. Math is an interactive Math site with students at Swarthmore college. They'll pose interesting problems, often geometric in nature, then publish the best solutions submitted. You can also ask questions. Don't be surprised if a famous Mathematician drops in to answer your question!

- Algebra Problem of the Week is another interactive site that posts a different Algebra 1 problem every two weeks. Submit your solution and see if it is published as one of the best. Remember, they know you can get the answer. It's the process that counts!

- MathMagic is an interactive problem-solving challenge that pairs student teams electronically, so you can dialog with other students about math. Try the category (7-9) or challenge yourself with those from (10-12).
- Play MANCALA, an ancient African game that helps you to develop logical thinking skills. Play against the computer to learn, then be sure to apply your skills in a real game against one of your classmates. I have a game board and stone markers in class!
