Pre-K Mathematics

Pre-K Mathematics is a pre-kindergarten mathematics curriculum designed for 4-year-old children from low-income families to address the socioeconomic gap in early mathematical knowledge. The intervention includes classroom small-group mathematics activities with concrete manipulatives conducted by teachers twice weekly (approximately 15-20 minutes per session) with groups of 4-6 children, covering six curriculum units: Counting and Number, Understanding Arithmetic Operations (Fall), Spatial Sense and Geometry, Patterns, Understanding Arithmetic Operations (Spring), and Measurement and Data. The curriculum also includes 16 home mathematics activities sent to parents throughout the year, a classroom math learning center, and supplemental math software (DLM Express) used at least once per week. Teachers receive intensive professional development including a 2-day introductory workshop, multi-day fall (4 days) and winter (3 days) workshops, and biweekly on-site support from curriculum coaches. The intervention uses a trainer-of-trainers model where internal facilitators are trained to support teachers' implementation with fidelity.
