  • identifying what data need to collected to answer a question or solve a problem, and suggesting strategies for collecting and presenting their data.  (Ask what is your favorite video game?  Record information and present data using tally marks).

-Description and Interpretation-

Students examine data and describe characteristics of the distribution, relate data to the situation from which they arose, and use data to answer questions convincingly and persuasively.

The learner will be able to:

  • describing and explaining data representations-a class-created graph representing different colors students are wearing.
  • providing an appropriate title for a graph.
  • exploring and identifying measure of center (mean, median).
  • teacher writes a summary about the results of a survey.
  • learning how different representations of the same set of data can communicate different information about data.
  • encouraging invented pictures/representations for portraying data sets.
  • generating questions and then collecting and interpreting data about topics relevant to them.

-Collection, Organization and Presentation of Data-

Students draw defensible inferences about unknown outcomes, make predictions, and identify the degree of confidence displayed in different formats.

The learner will be able to:

  • using their data to develop descriptions and theories about their world: How much are we reading each week?
  • designing and conducting surveys, experiments, and investigations: In what month do the most birthdays happen?
  • explaining how they reach a decision, giving reasons based on their data.
  • questioning each other about their conclusions.
  • searching for patterns in data so they can identify trends and make predictions.
