Great Sources of Rich Problems

This collection of resources will help teachers to find interesting and challenging problems that engage students in learning new concepts and developing new stategies. Several teacher packets from the Math Forum @ Drexel University provide a sample problem and all of the information you need to use it with your classes. The other sources include access to a variety of problems appropriate for elementary level children and offer suggestions about how to use them with your students.

This packet of information for teachers is designed to be used with the How Many Berries Did I Eat? Problem of the Week from the Math Forum collection for grades K to 2. The sample problem provides an exemplar of the type of problem teachers can use to promote students' mathematical thinking and reasoning and engage their interest. The key concept addressed in this problem is subtraction. The packet contains the sample problem, alignment to the Common Core State Standards, possible solutions, teaching suggestions, a print-ready copy of the problem, and a problem-specific scoring rubric.

This packet of information for teachers is designed to be used with the Dad's Cookies Problem of the Week from the Math Forum collection for grades 3 to 5. The sample problem provides an exemplar of the type of problem teachers can use to promote students' mathematical thinking and engage their interest. The key concepts addressed in this problem are fractions describing parts of a whole and addition. The packet contains the sample problem, alignment to the Common Core State Standards, an answer check, possible solutions, teaching suggestions, sample student responses, a print-ready copy of the problem, and a problem-specific scoring rubric.

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 website has thousands of free mathematics enrichment materials for teachers and learners from ages 5 to 19 years. All the resources are designed to develop subject knowledge, problem-solving, and mathematical thinking skills. The website is updated with new material on the first day of every month with fifteen problems and a number of games, articles and other resources. All are tagged with curriculum content links and challenge levels. Past issues, as far back as November 1999, can be accessed by a link on the home page.

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.
