2017-18 Problem of the Week Calendar

Links to the Packets, suggested Activity Series strategies, and Online Resources (and more!) are available from the individual problem page (linked from the titles below). Access to the problems is restricted to users who have subscribed to one of our membership services. More information is available on our Pricing Guide.

Mentor groups (indicated by X) make it possible for more students to receive free mentoring than is normally possible. This list is updated throughout the year.

* Students can submit to problems any time after they open. However, only solutions submitted before the next problem opens will be considered for inclusion in the posted solutions for the Math Fundamentals, Pre-Algebra, Algebra, and Geometry problems.

Teachers with Full Memberships or higher can also view the problems from the 2016-17 academic year.
