The Math Forum's Problems of the Week are designed to foster the growth of a mathematics community on the Internet. Mentors contribute to the elementary mathematics community by volunteering to reply to solutions submitted by students in grades three to six. Students discover the joy of exploring challenging, non-routine math problems with someone outside their regular classroom. Both students and mentors enhance communication skills as they discuss their problem-solving techniques. This site is very useful for teachers.
