Summary: Linear functions are an important part of the middle school mathematics curriculum. Students in the middle grades gain fluency by working with linear functions in a variety of representations. Presented in this article is an activity that was used with five eighthgrade classes at three different schools. The activity contains 15 cards that can be sorted to create 4 sets of cards, with each set representing one particular linear function. Some cards will not fit into any set, which automatically increases the cognitive demand of the task. (ERIC)
