Rainbow Tally Chart and Graph

Math Lesson


In the previous lesson, the kids learned that white light is really made up of the 7 colors in the spectrum.
In this activity, children can conduct a survey to find out their family and friends' favorite colors in the spectrum. They can follow up that activity by making a graph to display their data.

Materials
  • clipboard or notebook
  • pencil
  • ruler
  • crayons or markers

  • Have students make a list or chart of the 7 colors of the color spectrum (remember ROY G BIV).
                *red
                *orange
                *yellow
                *green
                *blue
                *indigo
                *violet
  • Have students poll their family and friends as to their favorite color. They should mark a tally for each vote.

  • Next they could count the votes and create a tally chart or frequency chart with their data.

Frequency Chart

    • Older children should use the data in the tally chart to create a bar or other graph to display their results.The graph should include:
                         ~ title
                        ~ 7 columns (for the 7 colors)
                        ~ 2 labeled axis
                         ~a numerical scale starting at zero
    • Finally students should explain their data (oral or written). Which color had the most votes? Which color had the fewest votes? Etc.
    • More advanced math students can also find the mean, medium, mode, maximum, minimum, and range for the data.
