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.

During the Activity
Distribute the page to the class.
Follow the Activity procedures:
Activity A:
Discuss the attributes of different buttons covering both similarities and differences
Activity B:
Sort the buttons by the chosen attribute and place them on the graphing mat in appropriate groups
Use the calculator to count the different types of buttons
Activity C:
Count the number of red and white buttons
Find the difference between the number of red and white buttons
