Students create bar graphs and find the range and mode of a set of data. They explore the relationship of vowels to consonants in their names. Illuminations provides activity sheets, a link to the bar graphing tool, and detailed instructions for completing the lesson.

Students will:

  • Collect and classify data.
  • Create a bar graph.
  • Compare bar graphs in different orientations.
  • Pose and answer questions about a set of data.
  • Find the range and the mode of a data set.

NCTM Standards and Expectations:

  • Represent data using tables and graphs such as line plots, bar graphs, and line graphs.
  • Compare different representations of the same data and evaluate how well each representation shows important aspects of the data.
