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.
