Current Problems of the Week

Important Announcement: Problems of the Week

Thank you for your interest in Problems of the Week. Effective January 1, 2018, NCTM is transitioning the Problems of the Week into an NCTM member benefit. During the transition period some things will change:

  • Student accounts will remain active, but student submissions will no longer be accepted for Problems of the Week.
  • NCTM is no longer selling subscriptions to this service as it will become a member benefit in April.
  • If you have a subscription, it will still be honored by NCTM. You will continue to have access to the Problems of the Week library and Current PoWs on for the time being. You will also be able to view and discuss the Current Problems of the Week through the MyNCTM member community, which is where all user community interaction will take place.
  • If you have not yet logged into MyNCTM (, we strongly encourage you to do so. MyNCTM is a member community where members can create and collaborate, network and access a member directory, upload and share resources in the resource library, ask questions and communicate with their peers. If you are an NCTM member, you should have full access to this community. If you are not an NCTM member, you will be part of a group with access to the Current Problems of the Week section.
