ab: From the text: Why is slope so important? How can I write an equation that
passes through these points? Why do we need to know three different
equations for the same parabola? These are just three of the questions
students often ask that demonstrate their difficulty connecting
different representations of relations and functions. Card-sorting
activities can be useful in helping students make sense of these
connections because they ask students to analyze multiple
representations of functions simultaneously. Two examples of
card-sorting activities are described here.
