Lesson 154 of 171

Students learn that a line graph is used to show change over time (such as the change in the population of a town over time), and the points on a line graph are plotted like the points on a coordinate grid. Note that a double line graph displays two sets of data on the same graph (such  more...

Students learn that a line graph is used to show change over time (such as the change in the population of a town over time), and the points on a line graph are plotted like the points on a coordinate grid. Note that a double line graph displays two sets of data on the same graph (such as the average height of boys vs. girls at different ages). Students are then asked to create line graphs using given data, and answer questions based on given line graphs.  less...
