Building a Thinking Classroom at St. Luke's: Engaging Students in Collaborative Problem-Solving

At St. Luke’s Episcopal School, we’re excited to introduce the “Thinking Classroom” approach in many of our math classes! Inspired by the research of Peter Liljedahl, this hands-on, collaborative method of learning is designed to engage students actively in problem-solving, helping them become deep and critical thinkers.


This summer, three of our teachers attended a session on “Building a Thinking Classroom” at the NCTM (National Council of Teachers of Mathematics) Conference in New Orleans, where they learned strategies to bring this approach to our classrooms. The Thinking Classroom framework involves:

  • Random Grouping: Younger students in K–2 work in pairs, while 3rd grade and beyond form groups of three.

  • Vertical Whiteboards: Each group works at a whiteboard stationed around the room, with a single marker and eraser to share.

  • Collaborative Problem Solving: Students stand up and work together to discuss and explore possible solutions, taking turns with the marker to contribute their ideas.


This dynamic approach gets every student on their feet and actively participating. As the lesson wraps up, the class gathers to review each board, discussing the different solutions each group explored. This process of sharing and reflecting on each other’s work reinforces collaborative learning and builds mathematical confidence.


We’re proud of the ways the Thinking Classroom model is transforming our students’ math experiences, encouraging them to engage in active discussions, learn from each other, and approach problems with creativity and curiosity. It’s all part of our commitment to nurturing strong, independent thinkers!
