Classroom Conversations: Understanding the Structures of Shapes: Connecting 2D and 3D Representations (Open to All)

Presented by Joana Conceição

During this session, we will share how first graders solved the "Can you build it?" task, where they were asked to build 3D shapes based on 2D depictions. Students' initial 3-D creations often need revision, and as they build and rebuild, they develop spatial relationships. Moving constantly between 2D and 3D leads to a stronger spatial sense that helps students unveil the shapes’ structures, an important topic in mathematics and recommended as a mathematical practice. This session will be hosted in Portuguese, with captions in English.
