Curcio, Frances R.; And Others
This document presents activities for use by middle school teachers which show how rational numbers and proportions are present in many real-world situations, including the collection and analysis of fractions, ratios, percents, and proportions, as well as rational number connections with geometry and similarity. The activities are divided into three content clusters: exploring and extending rational number concepts, applying rational number and proportion concepts, and making rational number connections with similarity. Each activity includes teacher notes on materials needed, teaching suggestions, lesson extensions, and ideas for integrating technology and alternative assessment. (MKR)
