ELM is funded by the Institute of Education Sciences. The goal of ELM is to study of an innovative kindergarten mathematics instructional program designed to improve early numeracy and prevent later math difficulties. This project was implemented in 67 classrooms in Dallas, and impacted the mathematics development of approximately 1,675 students. Data collection on this project ended in spring 2011.

This study examined the efficacy of a kindergarten math curriculum, ELM. The ELM curriculum is a comprehensive mathematics curriculum consisting of 120 lessons providing explicit instruction in (a) number operations, (b) geometry, (c) measurement, and (d) vocabulary. ELM is designed to address the learning needs of all students including at-risk students in the general education or tier 1 classroom setting. The study utilized a randomized block design, with classrooms assigned within schools to treatment and control. Sixty-four kindergarten classrooms stratified by region were randomly assigned within school to treatment (ELM) or control (standard district practices in kindergarten mathematics instruction) conditions. Proximal and distal measures of mathematics achievement were collected at pretest and posttest to measure student achievement.
