Description
Students first practice evaluating ratio tables for proportionality. Then they will use the ratio tables to create ordered pairs, and plot the points on a graph. They are taught to recognise a proportional graph by a straight line through the origin. There are several graphs in which to practice. The activity concludes with students finding proportionality in a word problem, by creating a table of values, graphing the points, and determining proportionality.
