Graph literacy is the ability to identify important features of a wide variety of graphs and relate those features to the context of the graphs—in other words, to increase your understanding of graphs' meaning. The Graph Literacy app is designed for middle school students to investigate equivalent graphs, learn to interpolate values, discover the difference between dependent and independent variables and more.
Learn about graphs that represent the same data, though they look different because they employ different scales.
Find linear trends on graphs and use these trends to interpolate values and find corresponding linear equations.
For various scenarios, determine the dependent and independent variables for display on a graph.
Learn to visually process an overall graph pattern or trend (shape) and to relate graph shapes and meanings.
Based on extensive research, the activities in the Graph Literacy app are aligned with the Common Core. Lesson plans are available on the Graph Literacy app support website.
The Graph Literacy project's primary goals are to: Develop and pilot test three to six free computer-based instructional activities that improve student graph comprehension, aimed especially at science students in grades 7 and 8, and develop a pilot assessment instrument focusing on students' comprehension of graphs.
