AI in the Geometry Classroom: An Interactive Exploration” facilitated by Melinda Koelling and Sayantan Basu   Short Description:In this hands-on session, we’ll briefly survey current AI platforms and then put them to the test with geometry-specific problems. We’ll explore their strengths and weaknesses together, followed by a group discussion on practical strategies for using AI as […]

“Transforming Instruction of Geometry—Emphasizing Reasoning and Proof (TIGER-AP) Community of Practice for Secondary Geometry Teachers” was facilitated by Orly Buchbinder and Ruthmae Sears on November 11, 2025. Let’s keep the discussion about their presentation going here on the blog! Short Description:This presentation will focus on the TIGER-AP – the online Community of Practice (CoP) of secondary […]

Four questions with Dorin Dumitrascu, Associate Professor of Mathematics at Adrian College My course is an axiomatic exploration of two-dimensional Euclidean geometry. I try to keep a balance between mathematical precision in exposition and allowing students to discover and share their study of shapes with their peers. This balancing act happens because I know that the […]

Introduction When the Danish mathematics professor Julius Petersen (1839-1910) published Metoder og teorier til løsning af geometriske konstruktionsopgaver (Methods and Theories for the Solution of Problems of Geometrical Constructions, Petersen, 1866), his handbook on geometrical constructions initially did not draw much attention. However, when a second addition appeared in 1879, it was translated into at […]
