Differentiation Have students write definitions of “generalizability,” “representation,” “short-term variability,” and “long term trends” and discuss as a class before moving on. Provide sentence stems to assist in completion of the group worksheets. Modifications See notes on the first page of the Jigsaw Cards for instructions about how to distribute cards to different group sizes. Extending the Learning Have students research any other forms of representations of data related to their phenomena. They might be surprised to discover how many different ways there are to represent the same data.
