## Developing Algebra-Ready Students for Middle School: Exploring the Impact of Early Algebra (LEAP 1)

## Abstract

In this first LEAP project, we constructed an Early Algebra Learning Progression [EALP] consisting of a curricular framework and progression developed by coordinating research, curricular, and mathematical perspectives; a Grades 3–5 instructional sequence based on the framework and progression; associated assessments; and levels of sophistication describing strategies observed in children’s mathematical work. We also conducted a preliminary study to examine the impact of our EALP’s instructional intervention as measured by our assessments and found that students who experienced the early algebra intervention outperformed comparison students on our early algebra assessment and were more apt by posttest to use algebraic strategies to solve problems.
