At the Riverside County Office of Education, which supports approximately 430,000 students across 23 districts, there has been a recognized need to enhance math education due to stagnant progress in statewide math assessments. Instead of merely updating textbooks or curricula, the focus has shifted to transforming the countywide math culture through evidence-based practices. This new approach aligns with national organizations and California’s revised math framework, aiming to increase student access, build positive identities, and foster student agency. The strategy emphasizes understanding the mathematics behind processes rather than repetitive procedural drills, encouraging students to share their thinking and connect math to their lives.
