Summary
District math leaders presented an overview of the TK–12 math curriculum—Bridges for elementary grades and CPM for secondary—highlighting a focus on conceptual understanding, student discourse, spiraling and assessments including plans to expand STAR as a common screener.
District math leaders presented an overview of Coronado Unified’s TK–12 math curriculum, describing why the district uses Bridges in the elementary grades and College Preparatory Mathematics (CPM) in middle and high school.
Why it matters: Curriculum and instructional approach determine classroom activities, teacher training and how parents can support student learning. The district said both curricula emphasize conceptual understanding, real-world application, student discourse and spiraled practice to build long-term retention.
Key takeaways - Elementary: Bridges in Mathematics (TK–5) focuses on conceptual number sense, visual models, hands-on routines (for example, a daily “number corner”), scaffolding and spiraling so students return to and build on earlier concepts.
- Secondary: CPM (6–12) centers on problem solving, collaboration in small teams, inquiry-driven lessons and “productive struggle,” where the teacher facilitates and questions rather than only lecturing. The curriculum is designed to promote reasoning, communication and perseverance.
- Alignment and transition: District presenters said Bridges and CPM are intentionally aligned; CPM recommends Bridges as a feeder curriculum. Both curricula emphasize student discourse and multiple representations of mathematical thinking.
- Assessments and data: The district uses CAASPP for state summative testing and local universal screeners (K–8) and piloted STAR at the high school this year. Staff plan to expand STAR as a K–12 common screener to allow progress monitoring at multiple points in the year and to integrate data into EduCLIMBER for teacher analysis.
- Implementation and professional learning: Presenters described multi-year adoption supports, vendor coaching, and in-district capacity building (train-the-trainer plans for Bridges). Staff noted onboarding of new teachers and maintaining fidelity are active priorities.
Context and next steps: Trustees and staff discussed the national spread of these curricula and the challenge families face when pedagogy differs from prior generations. District leaders said they offer parent resources and workshops to show how math is taught and urged families to use vendor parent materials and school resources. The district will continue professional learning and expand screening tools for coherent TK–12 monitoring.
