Mentor groups will be providing feedback to submitters in Problems of the Week over the next several weeks:

• Math Fundamentals from April 23 through June 3
• Geometry from April 30 through May 13
• Algebra from May 21 through June 3

Please have your students submit solutions. If they receive replies from a mentor, we hope you'll encourage them to revise. Not only will your students learn more, but the mentors will learn as well!

In 1996, when he was age 10, B.J. began compiling (with his father's help) links to educational websites. The site grew to include hundreds of sites that help students with their homework.

Recently re-launched, the site's math section is organized under these topics:

• General Math
• Algebra
• Calculus
• Elementary Level Math
• Geometry
• Trigonometry
• Math Tables, Definitions and Other Cool Stuff
