After completing this tutorial, you will be able to complete the following:

- Explain what a pictograph is.
- Analyze and answer questions about pictographs.
- Construct pictographs.

In this Activity Object, students are learning to construct pictographs. They will also analyze and answer questions about pictographs.

It is important to help build on the skills your students have learned in earlier grades about data collection. In 6th grade, students should begin to formulate questions that can be answered when data is collected, organized, and analyzed. Pictographs are one way to organize and analyze data.

Pictographs are one type of data display.

Also called picture graphs, this representation of data is where a picture or symbol is given a numerical value. The symbol can be divided into halves or quarters with numerical values that corresponds to half or quarter of the amount.

Pictographs are known to be the oldest way to record data, dating back to hieroglyphic writing. The Aztec stone of the sun is a famous example from early history of pictograph data documenting the Aztec calendar.

Today they are used quite frequently in mass media to communicate data in easy to read formats. They are primarily used to communicate statistics and social stratification.

The following data on the gasoline consumption for North American countries is represented in the pictograph below.

The following key vocabulary terms will be used throughout this Activity Object:

construct pictograph - the process of creating a picture graph by first creating a key with a symbol and giving it numerical value, and then by displaying the data in repeated symbols that correspond to the numbers, including half and quarter symbol images.

data - collection of natural phenomena descriptors which include the results of experience, observation and/or experimentation.

key - a place on the pictograph where the symbol is given a numerical value so someone reading the picture graph can interpret it

interpret pictograph - to explain the meaning of the pictures representing the data in the graph and derive conclusions about the data

pictograph - also known as a picture graph, a representation of data where a picture or symbol is given a numerical value, and then the symbol can be divided into half or quarters with numerical values that correspond to half or quarter the amount
