The authors examine the effects of 3 interventions designed to support Grades 2–5 children’s growth in measuring rectangular regions in different ways. Their findings indicate that creating a complete record of the structure of a 2-dimensional array—by drawing organized rows and columns of equal-sized unit squares—best supported children in conceptualizing how units were built, organized, and coordinated, leading to improved performance.
