Brief Abstract

GeoGebra's free Math Open Educational Recourses (OERs) are leading the way for educators to incorporate customizable student-centered discovery-based learning in any teaching modality. Come with your device and learn how to increase access, equity, and engagement as you create your own course specific Tarsia (9-square) puzzle in GeoGebra.

Extended Abstract

The participants will be able to incorporate the free digital tools of GeoGebra to promote student-centered discovery-based learning in their lessons that are accessible to all students equitably and independent of their learning environment. They will have the opportunity to share and model their lessons for group members as each will be able to play the role of student and teacher.

Success will be determined when each participant is able to create and share out their own Tarsia with their group.


10 minutes to discuss the history and mission of GeoGebra.

10 minutes to explore the GeoGebra calculators and discuss how these dynamic tools can be used to change the way one teaches.

15 minutes to explore a variety of free community created resources and to learn how to share resources out to a group.

25 minutes to create their own personal course specific Tarsia (9-square).

25 minutes to share out their creations with their group and monitor group activity.

5 minutes to ask questions

Participants will have the opportunity to create, share, and model their Tarsia (9-square) puzzle with group members at their table, as each person at the table will have the opportunity to play the role of both student and teacher. Teachers will be able to monitor their students' (table members') activity and progress with the Tarsia. Students at the table will have the opportunity to work through their teachers' (table members') course specific puzzle. Table members will have the opportunity to collaborate and help each other both from the student and teacher perspective. Success will be determined when each participant (table member) is able to create/share their own, and interact with another's resource at their table.
