In this live Tier 1 Interventions session, Cheri Dotterer and Jonily Zupancic take you inside a Level 2 Mastery Math Method class as they explore the classic Locker Problem — one of the “Dirty Dozen” reference tasks students revisit year after year.
Jonily demonstrates how these timeless math tasks deepen logic, number sense, and symbolic understanding, while Cheri highlights how process time and conceptual exposure create space for authentic learning.
Discover why exposure before mastery can transform math instruction, how to nurture student vulnerability, and what happens when teachers stop rushing to confirm or deny answers.
🎧 Perfect for math educators, OTs, and interventionists ready to “uplevel” their practice and create classrooms where curiosity thrives.
💬 Drop your thoughts and experiences in the comments—start the conversation and build the movement because every student deserves to feel like a mathematician.
