Math Idea #3
Graphing
Objective:
The students will remember and record what fruits and
vegetables they ate or drank yesterday, make a table of the
results with other students, and construct a simple bar graph
of the results. By graphing the results of their individual
food records, they will see a visual representation that can
be used to compare results of others in their group.
Rationale:
Much information about fruits and vegetables is presented in
the "5 A Day Adventures". The activity suggested here teaches
students how to condense this information into easy to read
graphs. The graphs also make it easier to compare pieces of
information.
Materials:
"What Fruits and Vegetables Did You Eat Or Drink Yesterday"
Student Activity Sheet
"What Fruits and Vegetables Did You Eat Or Drink Yesterday"
Group Summary Table
"How Many Fruits and Vegetables Did You Eat Yesterday" graph
paper.
Crayons or markers
Introduction:
* Have each student fill out the "What Fruits and
Vegetables Did You Eat or Drink Yesterday" Student
Activity Sheet to determine how many fruits and
vegetables were eaten.
* Discuss reasons why writing down what you eat is a good
way to assess eating habits and the first step in
reaching the 5 a Day goal.
* Discuss with students the reasons for using graphs
(represents information in an easy to read manner; easy
to compare information).
* Be sure to discuss the importance of titles and labeling
the axes.
Class/Group Activity:
* Have students divide into small groups and give each
group graph paper and crayons or markers to make a graph
of the groups results.
* Note the national average line for fruits and vegetables
eaten daily at 2 1/2 servings per day, and the 5 a Day
goal line on the graph paper.
Individual Activity:
* Have students keep a record of fruits and vegetables
eaten over a 5 day time period, and graph their
individual results. Have them compare daily results.
What is the daily average? How many days did they
reach 5 a Day. On which day(s) did they reach their
goal? Did they think this activity made any difference
in their eating habits.
Related Activities:
* Conduct a classroom survey and have students rank their
top 5 favorite fruits or vegetables, and graph the
results, and then use the graph to discuss which
vegetable got the most votes, which got second, how
many people voted for which vegetable, why they think a
particular fruit or vegetable got the most votes.
* The "5 A Day Adventures" CD-ROM section, Salad Factory,
contains information on the content of Vitamin A,
Vitamin C, and Fiber for 16 fruits and vegetables. Using
this section, students could be asked to graph how many
fruits and vegetables are good sources of each.
* Have students compare their favorite vegetables to the
ones that are good sources of Vitamin A, Vitamin C, and
Fiber. What are children eating?
* Students may survey the other classes in the school about
favorite fruits and vegetables. The information could be
graphed and displayed in the school cafeteria.
* Have students graph the favorite fruits or vegetables of
family members or neighbors.
