#### Activity Overview

In this activity, students sort and classify buttons by their attributes and display their findings on a graphing mat. They represent this information in the form a graph of their choice. They learn to use inequalities and compare quantities of buttons having specific attributes. Students also, explore the use of a constant function to do skip counting.
