Mathematical Explorations: Freshwater Scarcity: A Proportional Representation
King, Alessandra
Mathematics Teaching in the Middle School, v20 n3 p178-182 Oct 2014
Middle school students' mathematical understanding benefits from connecting mathematics to other content areas in the curriculum. This month's activity explores the issue of the scarcity of freshwater, a natural resource (activity sheets are included). This activity concentrates on the critical areas mentioned in the Common Core State Standards for Mathematics (CCSSM) that call for greater focus on fewer topics (ratios and proportional relationship for the middle school grades) and coherence (using those mathematical skills to solve real-life word problems). In this activity, the water contained in a large water dispenser represents all the water on Earth. Given the composition of the water on the planet, the students replicate the same composition with the water in the dispenser.
