• Lightbulb Students will be identifying the independent and dependent quantities when given a table or graph. Tables make it a little easier to identify these two quantities, but on a graph, this is more difficult. It is important to note that the independent quantity is noted by the x-axis. This is the starting point when graphing, so it makes sense that the independent quantity would be located here. The dependent quantity is shown on the y-axis. It is best when practicing that student practice with tables and graphs demonstrating the same scenario simultaneously. This helps ensure they are making connections between the two representations.
