Organize, represent, and interpret data with up to three categories; ask and answer questions about the total number of data points, how many in each category, and how many more or less are in one category than in another.


Quarter 4

Organize and represent data with up to three categories and Interpret data with up to three categories. Ask and answer questions about:

  • the total number of data points
  • how many in each category
  • how many more or less are in one category than in another

Enduring Understanding

Measurement processes are used in everyday life to describe and quantify the world.
Data displays describe and represent data in alternative ways.

Essential Questions

Why does "what" we measure influence "how" we measure?
Why display data in different ways?

About the Math

Collecting and organizing data is an important part of mathematics and lends itself to problem solving situations. It is important that students collect the data by asking questions of the class or taking surveys. Once the data has been collected, it needs to be organized and then analyzed. Students should use tally marks, bar graphs and pictographs to organize the data. Once the data is organized students need to draw conclusions from what the data is saying.

Rich Tasks for Multiple Means of Expression, Engagement, and Representation (UDL)


Problem: Farmer Brown has seventeen animals. He has four different types of animals. Draw a graph to show what they might be. (Lilburn and Ciurak, Investigations, Tasks and Rubrics to Teach and Assess Math,p 36)

On a graph about pets owned by children in our class, I saw that there were more cats than dogs and more dogs than gerbils. What might the graph look like? Collecting and organizing data is an important part of mathematics and lends itself to problem solving situations. It is important that students collect the data by asking questions of the class or taking surveys. Once the data has been collected, it needs to be organized and then analyzed.

Journal Prompts:
  • Decide on a yes/no question that you would like to collect data on. Ask 8 children your question and record their answers. What did you find out?
  • Take a scoop of pattern blocks and sort them. Use pictures, numbers and/or words to show how you sorted them.
