The historical movement
New Math was not a single textbook or one national curriculum. ERIC’s historical account describes a U.S. reform movement extending from the early 1950s into the late 1970s, while Christopher J. Phillips’s The New Math: A Political History places the movement within Cold War concerns, National Science Foundation curriculum projects, and efforts to make school mathematics more structural and abstract.
What the 2008 math panel actually found
The National Mathematics Advisory Panel did not endorse a simple “traditional versus modern” binary. It said conceptual understanding, computational fluency, and problem solving are mutually supportive. It also explicitly linked whole-number proficiency to automatic recall of basic facts and fluency with standard algorithms, and identified whole numbers and fractions as critical foundations for algebra.

Developmental readiness
Research on prefrontal cortex maturation describes development as continuing across adolescence and into early adulthood. This research provides useful context when considering the developmental readiness of younger students for increasingly abstract material.
