Learn, Apply, and Reflect with the S3D Approach
The videos below are designed to support your understanding and implementation of the S3D Approach for strengthening student-to-student discourse in small-group math settings. Whether you're just getting started or looking to deepen your practice, videos offer practical guidance, real classroom examples, and tool demonstrations to help you along the way.
The collection is organized into four series to help you navigate easily:
🔹 Series 1: Introducing the S3D Approach
Overview of the four steps and how they work together to support discourse across two phases.
🔹 Series 2: Talk Tools – Paper-and-Pencil
Introductions and tips for using each of the four tools in their printable versions.
🔹 Series 3: Talk Tools in App
A walkthrough of the S3D App and how to use each tool to track and support student discourse digitally.
🔹 Series 4: Talk Tools in Action with App
Real classroom examples showing how a teacher used the app-based tools in context.
