In the first activity, students are introduced to the idea of using one symbol in a picture graph rather than a picture. They may find it easier and more efficient to use a symbol when drawing their graphs. In the second activity, students attend to the features of bar graphs as they draw a bar graph to represent a given set of categorical data. The work of this lesson connects to upcoming lessons as students move from a discrete representation of numbers with the picture graph to a continuous representation of numbers with the bar graph. In later lessons, students use bar graphs to help them understand tape diagrams. Students use the graphs they create in this lesson in the following lesson.
