The goal of this project is to replicate the efficacy of an intensive Tier 2 math intervention, Pre-K Mathematics Tutorial (PKMT), for pre-k children at risk for mathematics difficulties, and compare the relative effectiveness of two delivery models (Pull-Out vs. In-Class) for implementing the intervention. Math difficulties occur early in childhood and are associated with negative long-term outcomes. PKMT is designed to address these difficulties by providing intensive instruction on a core...

The purpose of this project is to refine, extend, and validate a number sense screener for students from prekindergarten through Grade 1. Number sense-the knowledge of number, number relations, and number operations-is highly predictive of later math success and underlies many difficulties students have in mathematics. Being able to identify students who have difficulties with number sense early in development is critical to providing educational interventions that promote readiness and succ...

Most public preschool and kindergarten programs spend little time on mathematics. In addition, the mathematics curricula typically used in pre-kindergarten and kindergarten are not evidence-based, effective mathematics curricula and share two common design flaws. First, the content included is typically too broad and thus fails to systematically focus on building student understanding of key math content. Second, most curricula are not designed to address the specific mathematics instruction...
