Constructing Fractions as Countable Numbers:

A Pathway to Fluency with Understanding

Students count to develop a concept of whole numbers which leads to mathematical operations. See how fractions are developed as countable number concepts using research on student thinking. Connecting students’ understanding of whole number operations and fractional operations leads to conceptual understanding and procedural fluency.

AIMS Center Presenter

Brook Lewis is a Research Associate at the AIMS Center for Math and Science Foundation, working with a team investigating research on how children come to know mathematics. Prior to her work with AIMS, she began as a High School mathematics teacher in the Central Valley, and has taught middle school math as well. Brook also gained experience in the public education system as a department leader, instructional coach, education consultant, and curriculum developer. She is determined to understand and translate current research in mathematics education in order to support students in learning, and teachers in the classroom. Although Brook has experience teaching most math courses in High School, her focus was with students that struggled with mathematics which has fueled her passion to work in the realm of research, in order to address the needs in math education. As a graduate from Fresno State University, Brook earned a BA in Mathematics and an MA in Education.
