Welcome to The Problem Site, a site fueled by a passion to provide interesting, informative, and valuable content to educators and students. We have an enormous collection of math problems, physics problems, brain teasers, and puzzles written by educators. We also have a fine collection of educational games. These games aren't all fancy graphics and silliness; the focus is on the educational value for students, so those who play our games will get the most puzzling, problem solving, and learning, in a compact time frame. Our games include word games, math games, strategy games, and even a handful of games specifically designed for young children. And if all that isn't enough, we also have printable mazes, worksheets, and vocabulary lists, and quizzes on a variety of subjects. The list of icons below will help you get started finding the resources you want.
