One Task, Multiple Proportional Reasoning Strategies
Brakoniecki, Aaron; Amador, Julie M.; Glassmeyer, David M.
Mathematics Teacher: Learning and Teaching PK-12, v114 n1 p33-40 Jan 2021
This article examines a common proportional reasoning problem used in schools, often referred to as the Orange Juice task. The authors show how these six strategies described by Nikula (e.g., Unitizing, Norming, etc.) and one additional strategy can be used to either solve or make progress in the Orange Juice task. The article presents work from teachers who solved this task and show connections among the strategies, illustrating opportunities for teachers to connect proportional reasoning strategies in problems such as this.
