Math Pickle is a free site that offers dozens of fun and challenging math puzzles for students of all ages. The puzzles are designed to foster collaborative problem solving over the course of 45 to 60 minutes. Almost all of the puzzles are presented as a series of small, connected problems that students need to solve to complete the puzzle presented to them. The puzzles can be viewed as slides and or downloaded as PDFs.
Applications for Education
Math Pickle arranges puzzles by grade level and topic. The puzzles can provide you with a new way to challenge your students to use their mathematics and reasoning skills. The puzzles are designed so that all students eventually experience a "failure" and a "break-through" during the process of completing the puzzle with a group.
