### 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

Directions

• 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.
