# Lesson 10

Usemos gráficas de dibujos y gráficas de barras para representar datos

### Lesson Purpose

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.

### Lesson Narrative

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.
