The following content should be taught in earlier grades according to the ACOS:


Kindergarten
  • Complete data displays such as single-loop Venn diagrams and yes/no charts using real object, concrete representations, or pictorial representation.
    • Responding to questions for the purpose of data collection

First Grade
  • Organize objects or information into predetermined and labeled data displays, including pictographs, tally charts, bar graphs, or double-loop Venn diagrams.
    • Generating simple questions for data collection
    • Creating displays with appropriate labels

Second Grade
  • Create displays, including appropriate labels, for a given set of data using pictographs, tally charts, bar graphs, or single- or double-loop Venn diagrams.
    • Interpreting graphic displays

Third Grade
  • Recognize data as either categorical or numerical.
    • Compare related data sets

Fourth Grade
  • Represent categorical data using tables and graphs, including bar graphs, line graphs, and line plots.
    • Collecting data using observations, surveys, or experiments
    • Creating tally charts to represent data collected from real-life situations
  • Represent numerical data using tables and graphs, including bar graphs and line graphs.

Fifth Grade
  • Analyze data collected from a survey or experiment to distinguish between what the data show and what might account for the results.
    • Evaluating different representations of the same data to determine how well each representation show important aspects of the data
    • Using given measures of central tendency (mean, median, and mode) to analyze data

Sixth Grade
  • Interpret information from bar graphs, line graphs, and circle graphs.
