Usemos gráficas de dibujos y gráficas de barras para representar datos
Grado 2
Preparation
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. 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.
- Engagement
None
- Represent given data using a picture graph and a bar graph.
- Hagamos nuestras propias gráficas de dibujos y de barras.
Required Preparation
Activity 1
- Each student needs 1 data table from the blackline master. Each student in a group of 2 may receive different data tables.
