Math instruction is often not optimal and may include tactics and philosophies that are at odds with the research evidence on how children actually learn and what constitutes effective instruction. Much like the science of reading has raised the bar for instructional stewardship in reading, math must follow suit so that more children have stable access to the effective math instruction needed to open doors to their future lives including college enrollment and completion. This session will ground attendees in the science of math and articulate the effective ingredients of evidence-based math instruction including what to look for in core curricula and how to supplement your core to maximize learning gains. Attendees will take away tactics to try right away in their own settings and directed to web-based resources to start their own work to adopt science-based math instruction within their MTSS (Multi-tiered system of support) structures. How-to details and examples will be provided for screening in math, delivering class-wide math intervention, and supporting systemic changes to cultivate math gains in classrooms. Free print and digital resources will be provided.
