LEAP 1: The Impact of Early Algebra on Students' Algebra Readiness

This project is testing the effectiveness of a comprehensive, longitudinal early algebra intervention in elementary grades 3-5 on middle-school algebra-readiness. This project draws from past project researchers’ development of an efficacious grade 3-7 early algebra learning progression, assessments, and professional development model.

LEAP 2: Developing Algebra-Ready Students for Middle School: Exploring the Impact of Early Algebra


This project is developing and testing a curricular learning progression of early algebra objectives and activities for students in grades 3 - 5. The goal of the work is to provide teachers with curricular guidance, instructional resources, and assessment tools that are useful in preparing students for success in the study of algebra at the middle grade level.

This project is a transfer from the National Science Foundation.

LEAP 3: The Impact of a Teacher-Led Early Algebra Intervention on Children's Algebra-Readiness for Middle School

Early algebra is viewed as a critical means for preparing students for success in a more formal study of algebra in middle and secondary grades. However, this premise has been virtually unexplored. Therefore, the primary purpose of this project is to (1) measure the effectiveness of a teacher-led early algebra intervention, in demographically diverse settings, on children’s algebra readiness for middle school and (2) assess the fidelity with which elementary teachers implement the intervention in authentic, intact classrooms.

We will use a cluster randomized trial research design where treatment is implemented at the school level to test the effectiveness of our early algebra intervention as the participants advance from grades 3–6.

Key outcomes include growth in students’ understanding of core algebraic concepts and algebra readiness, as well as general mathematical knowledge, because of the early algebra intervention.
