New Features in the Problems of the Week

The Activity Series provides a framework and classroom activities to develop problem solving strategies and mathematical communication. This coherent sequence runs in parallel with the Current Problems of the Week, but can be used with other non-routine problems of your choosing.

This year we've added an option to print the scenario without the question to solve. This supports our popular "Noticing and Wondering" approach, described in the first "Understanding the Problem" activities and in our article (PDF format):

We've also added a student worksheet to help organize their work.

Math Forum Professional Development Courses

We have a new round of professional development courses starting September 17. The first two courses below are designed to help Problem of the Week members make the most of their PoW memberships.

  • PoW Class Membership: Resources & Strategies for Effective Implementation
  • Differentiated Math Instruction: Using Rich Problems to Reach All Learners
  • Problem Solving Strategies

Discovery Education's Puzzlemaker

Puzzlemaker is a puzzle generation tool for teachers, students, and parents. Create and print customized word searches, criss-crosses, and other math puzzles using your vocabulary lists.

Make your own Math Squares or Number Blocks, or try your hand at a Math Mind Game.


The CERES Project is the Center for Educational RESources. Through funding from NASA, faculty at Montana State University and classroom teachers from across the nation have developed an extensive library of on-line and interactive K-12 science education materials for teaching astronomy. In addition, CERES has developed several on-line NASA data search engines, listed on the site under "Classroom Resources."

Educational activities fall into one of these NASA themes:

  • The Sun-Earth Connections
  • The Search for Origins
  • Structure and Evolution of the Universe
  • Exploration of the Solar System
