Math
Lesson
for Rainbow Day
Objective:
The
students will create and interpret a graph of their
favorite colors.

Materials
 A large piece of butcher
paper divided into 7 columns for graphing.
 Index cards, or pieces of
paper to fill in the graph
 Crayons, markers, or
colored pencils
 Favorite
Color Worksheet (Problems # 6 and 7 will need the
blanks filled in once the graph is complete.)
 Graph paper, if desired.

Procedure
 Distribute the index cards
(or small square pieces of paper). Have the
students pick which rainbow color is their favorite 
red, orange, yellow, green, blue, indigo, or
violet. They should then color the index card
their favorite color.
 Have the students place
their card in the appropriate column on the chart
paper graph.
 If desired, have the
students copy the graph onto graph paper of their own.
 Discuss and interpret the
graph. Ask questions such as, "Which color
has the most votes?", "Which has the
least?". The depth of the questions
will depend on the age level of the students.
 Pass out the Favorite
Color Worksheet, if appropriate. Problems
number 6 and 7 will need the blanks filled in once the
graph is complete.

Other
Lesson Ideas
 If the students have worn
their favorite color to school on this day, make a
human (real) graph.
 Have the students write
math problems in which the answer is 7 (due to the 7
colors in the rainbow).
 Assign each color a number
 red=1, orange=2, yellow=3, green=4, blue=5,
indigo=6, and violet=7. Have the students do
math problems in this "color secret
code". For example, using their crayons, a
red box + an orange box = a yellow box. The
problems may be more complicated, depending on the age
level.
