Several sets of a materials have been developed through various PTMT projects. All PTMT materials are based on research on teaching and learning mathematics with technology and have been iteratively revised based on empirical studies with teachers. For more information read our research-based **Guiding Framework (PDF) **and see the various research studies under Impact.

Materials are organized in collections and can be accessed through the blocks below. Materials within a collection are envisioned to be used together, though many teacher educators will use materials across several collections to form the basis of content for a course within a mathematics teacher education program.

**Examining Students’ Practices in Algebra and Function**

These materials connect with the Teaching Algebra materials to support teachers’ development of pedagogical skills related to professional noticing of student thinking and engaging in productive discussions in technology-mediated learning environments. Teachers engage in tasks and analyze videos of students’ work.

**Teaching Algebra**

The Teaching Algebra materials consist of 7 chapters that provide strategies for teaching algebra with dynamic technology explorations of important topics such as variables, equality, rate of change, and functions.

**Teaching Statistics Investigations**

This set of materials includes four chapters that prepare teachers to use large multivariate data and a new free online tool, CODAP, to engage in similar investigations as in Chapters 1-4 of the Teaching Data Analysis and Probability materials.

**Teaching Data Analysis and Probability**

This set of materials includes 6 chapters that utilize tools such as TinkerPlots, Fathom, Excel, and graphing calculators to engage teachers in statistics investigations using multivariate data. Topics include learning to teach distributions, variability, bivariate relationships, probability, and simulations.

**New Teaching Geometry**

Coming Soon…………………

**Teaching Geometry**

The 7 chapters in the Teaching Geometry materials engage teachers with how dynamic approaches to geometry can change students’ understanding of concepts such as polygon properties, transformations, similarity, and symmetry.

**Voices from the Field**

A collection of video clips representing how real teachers use technology in their mathematics classrooms. Some clips illustrate how teachers and students use technology in lessons. Other clips show teachers and experts discussing issues related to their planning and implementation of technology.

**Forging Connections Between Geometry and Functions**

A collection of materials on an ** external site** that were developed through a PTMT-related project. Activities use web-based Sketchpad activities to develop deeper understandings of functions through a geometric approach.
