This product contains a very diverse card sort activity. The entire card sort is made up of matching the words, equation, table, graph, and constant of proportionality. You can differentiate by using only table and graphs, or words, table and graph or however it fits your needs. You can also just put each card in main category of proportional or non-proportional. When you print this out you may have to check the y-axis labeling - click on it and change line spacing to 0. I do this but when I pull it back up it is back to odd numbering. Hopefully, you will not have a problem, but if you do it is an easy fix.
