Choosing Between Home Appliances: Benefits to the Planet and Your Wallet part of SISL:2012 Sustainability in Math Workshop:Activities

In this activity, students compare various options for purchasing new home appliances: refrigerators, washing machines, clothes dryers, dishwashers, microwave ovens, electric ranges, and window air conditioning units. Students compare the energy usage of more efficient models to less energy efficient models, and calculate the "payback period" in cases for which the purchase price for the energy efficient model is higher, but the energy savings over time make it less expensive in the long run.

Final Quantitative Reasoning Project: Planning a Sesquicentennial Celebration part of National Numeracy Network:Teaching Resources:Quantitative Writing:Examples

This project serves as the final project for Introduction to Quantitative Reasoning, a course for first-year students who need to improve their quantitative skills before they may enroll in quantitative coursework at Wellesley College. The project gives students practice spelling out assumptions, applying mathematical models, creating tables and graphs, and explaining calculations and models in writing.

Understanding Exponential Growth in the Context of Population Models part of National Numeracy Network:Teaching Resources:Quantitative Writing:Examples

This set of three assignments gives students practice with exponential models in the context of the growing human population. These assignments are designed to: help students see that growth at a constant percentage rate implies repeated doublings over a specific time interval give students practice describing differences (in growth rates and in population sizes) in both absolute and relative terms introduce students to real population data, and get students to think about the limitations of the simple exponential model and consider the multiple factors that affect population growth. The assignments include: calculations creation of tables and graphs a short comparison and contrast exercise, and a critique of the model.
