Each lesson is aligned with NCTM Standards and is appropriate for a variety of math courses and student levels. Students explore concepts in an open-ended format that takes them beyond what is covered in a typical curriculum.
Students engage in building, visualizing, conjecturing, solving, and creating.
In the process of active problem solving, students discover patterns, relationships, and underlying mathematical processes. The lessons are appropriate for individual work, partners, or small groups. Activities can be shaped to fit student needs and to coordinate with the primary curriculum source. Each activity is accompanied by a complete lesson plan. These contain an overview of the activity, materials needed, suggestions for introducing and discussing the activity, and solutions and extensions.
