Free Mentoring Opportunities

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

  • Math Fundamentals from February 23 - March 8
  • Pre-Algebra from February 16 - March 1
  • Algebra from February 9 - 22 and February 23 - March 8

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!
