This document outlines an approach to problem-based learning (PBL) in mathematics classrooms. It discusses how PBL can help develop higher-order thinking skills and align with common core standards. PBL is presented as an alternative to traditional lecture-based math classes where the teacher is the sole authority. The document describes key aspects of PBL pedagogy including scaffolded problems, connected curriculum, shared authority between teachers and students, and justification of ideas rather than prescription. Examples of PBL techniques are provided, such as modeling, coaching, and fading support. The benefits and challenges of implementing PBL are also addressed.
