PRESENTED BY: Orly Buchbinder, Ruthmae Sears

This presentation will focus on the TIGER-AP – the online Community of Practice (CoP) of secondary (Grades 6-12) geometry teachers from New Hampshire and Florida. TIGER-AP occurred between January and April 2025, in which about 20 teachers met once a month for two hours. The CoP encouraged geometry teachers to strengthen their technological pedagogical content knowledge, share instructional strategies and experiences, integrate technological tools during instruction (such as FullProof.io), work collaboratively, and support students’ abilities to construct proofs and demonstrate proficiency in geometrical reasoning.
