Program Description

"Whole Number Foundations Level K (WNF-K) is designed to accelerate the mathematics achievement of kindergarten students who are at risk for mathematics difficulties by focusing primarily on early number sense, numbers and operations, and vocabulary. The primary aim of WNF-K is mastery of number concepts and skills through the number 20. •Tier 2 small-group intervention provided in addition to core (Tier 1) instruction •50 lessons delivered three to five times per week in 20-minute sessions •Instructional objectives aligned with the Common Core State Standards in mathematics for kindergarten •Research suggests WNF-K has a beneficial impact on student math achievement. •The National Center on Intensive Intervention rated a study about the effectiveness of WNF-K as having “partially convincing evidence” regarding the study design, and “convincing evidence” regarding participants, fidelity of implementation, and broad math outcome measures. •Available in Spanish as Fundamentos de los Números Enteros: Nivel K"

Research Summary

Two randomized controlled studies indicated significant positive outcomes for Kindergarten students in intervention groups in overall mathematics achievement and performance when compared with their control counterparts. An ESSA evaluation also indicated strong evidence for the efficacy of the program. Therefore, there is sufficient peer reviewed evidence to support the efficacy of this intervention.
