Technology Problems of the Week (tPoWs) are freely accessible problem-solving challenges, modeled on the Math Forum’s Problems of the Week, that take advantage of interactive mathematics tools such as Java applets, TI-Nspire™, The Geometer's Sketchpad®, Fathom™, or spreadsheets. A login is required. Teachers may choose a free class membership, providing the ability to create classes, create student logins, and use the Math Forum’s online mentoring and feedback system or choose a free individual membership, providing individual access to view the problems as well as any available teacher resources. Free student memberships are also available. Problems include hints and answer checks.

This webpage offers rationale for writing in math class and contains links to word problems from kindergarten through high school. The problems cover a variety of strands and lend themselves to written explanations and visual representations. Each grade level (above grade 2) also contains a set of problems selected according to problem solving strategy and a description of the strategies. Each grade level page includes a link to a downloadable presentation (pdf) on math problem solving.
