# Samples of the Problems of the Week

All of our problems were originally written with a specific grade range in mind, which is indicated here. Over the years, however, many teachers have shared with us that their students have had successful problem solving experiences in their classrooms when exploring problems from many different levels.

See below for an explanation of the accompanying support materials.

## Support Materials

Many of our problems are accompanied by the following:

• Teacher Packets include the problem and "answer check" (the answer we provide students after they submit their solution to a problem), a range of solutions we write, our problem-specific scoring rubric, tips about how to introduce the problem to students, and ideas about how to move students forward. Many also include alignment to the Common Core State Standards and samples of student work and comments about the solutions based on a category from the scoring rubric. Over 300 of our problems currently have packets.

• Scoring Rubrics help you think about how to score your students' solutions using our six-category scoring grid. Over 300 of our problems currently have problem-specific rubrics.

• Scenarios provide a version of the problem set-up, without the question. This is a good way to introduce the Problems of the Week in your classroom and have students focus on the story of the problem and generate as much relevant mathematics as possible. Over 300 of our problems currently have scenarios.
