4.D.1.2 Use tables, bar graphs, timelines, and Venn diagrams to display data sets. The data may include benchmark fractions or decimals (¼, ⅓, ½, ⅔, ¾, 0.25, 0.50, 0.75).
In a Nutshell
Use tables, bar graphs, timelines, and Venn diagrams to display data sets. The data may include fractions, decimals, or whole numbers.
Student Actions

Teacher Actions
|
-
Develop a productive mathematical disposition by generating ideas for data collection activities.
-
Develop a deep and flexible conceptual understanding by generating or gathering data and displaying data involving decimals and fractions.
-
Develop strategies for problem solving by choosing the most appropriate method to display data.
-
Develop the ability to communicate mathematically by using an appropriate scale and key in a data representation. (If all of my data points are between 1-10 my scale won’t be 10.)
-
Develop mathematical reasoning by using graphs and tables to find patterns in data.
-
Develop the ability to communicate mathematically by analyzing data with classmates and communicating information in data displays.
|
-
Implement tasks that promote reasoning and problem solving by giving students the opportunity to use data involving decimals, fractions, and appropriate data displays.
-
Support productive struggle as students attempt different ways of representing data. Allow them to grapple with which representation is most appropriate and effective.
-
Pose purposeful questions to assess and advance students’ reasoning:
-
Why is this display the most appropriate?
-
Could you show this data using another representation? Which would you choose? Why?
-
What would be the least effective data representation? Why?

Key Understandings
|
Misconceptions
|
-
Data can be displayed in tables, bar graphs, timelines, and Venn diagrams. Not all displays are appropriate for all data.
-
The increments used for displaying data depend on the data collected.
-
Data may include decimals and fractions.
-
A graph is a visual representation of data.
|
-
The scale used in bar graphs and timelines is not important.
-
The scale only needs to include the numbers in the data, and the increments do not need to be equal.
-
The scale is automatically 1.
-
All data displays are equally effective in representing any given data set.
-
Data sets only include whole numbers.
-
All sections of a Venn diagram must contain data.
