Triangle Congruence Theorems: Developing Reasoning Through Informal Arguments
This session will include the description of an activity used to introduce triangle congruence theorems in a high school geometry course. The purpose of this activity is to develop students’ reasoning and justification through informal arguments prior to writing proofs using triangle congruence theorems. Participants will discuss the number of elements needed to prove two triangles congruent. Participants will then be assigned a possible triangle congruence theorem. Group discussion will follow, including arguments formulated by participants, as well as student examples from high school geometry students. The session will conclude with a summary of the activity and its use for implementation in a high school geometry course.

Using Technology to Develop Discourse in the High School Math Classroom
Imagine a classroom full of students and devices. What does it sound like? Too often, the introduction of technology into a high school math classroom brings with it silence. How can we leverage technology to create more social and creative classrooms? How can we use technology to include rather than isolate? Bring a device, bring your experience, and bring your voice as we explore these ideas together.
