Lesson 10

The purpose of this lesson is for students to attend to the features of picture graphs and bar graphs as they represent a given set of categorical data in picture graphs and bar graphs.

In the first activity, students are introduced to the idea of using one symbol in a picture graph rather than a picture based on the category. 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. From there, students use bar graphs to help them understand tape diagrams in later lessons.
Students use the graphs they create in this lesson in the following lesson.

• Each student needs 1 data table from the blackline master. Each student in a group of 2 may receive different data tables.
