“C
lass, I would like to do a survey on your favorite
summer drink. Can you cite some ways to show
the results of the survey?” asked the teacher. But the
students did not have any idea at all.
“Well, a pictograph can help us. A pictograph is a graph
that uses pictures or symbols to show data. Here is an example of a
pictograph,” the teacher said while showing a chart.
Cans Collected
← title
Class I-A
= 5 cans ← key
Class I-B
Class I-C
← symbol
“The pictograph can help us compare data. It has three parts,
namely title, symbol, and key,” said the teacher. “What is the title
of the pictograph?”
“‘Cans Collected’,” replied Emily.
“What is the key used in the pictograph. What does it tell
you?” asked the teacher.
“The key tells us that each symbol shows five cans. Since
will be equal to 10 cans,” added Emily.
shows five cans,
“What is the symbol used to compare the data?” asked the
teacher.
“A can was used as a symbol,” replied Frank.
“Remember that the symbol to be used should be related to the
title of the pictograph,” said the teacher.

“D
o you have a favorite animal?” Mrs. Mercado asked her
students.
Everybody yelled the names of their favorite animal.
“You can take a survey of your classmates in order to find out
which animal is the most popular,” suggested Mrs. Mercado.
“Teacher, could you please help us make the
survey?” asked the students.
“Of course,” replied the teacher. “Let us work
together. Now, think of different animals your
classmates can vote for. Then make a table to show
the choices.”
The children immediately worked on their table.
“Leah, please present your work on the board,” instructed the
teacher.
Leah stood up quickly. She had her work written on a manila
paper. She posted it on the board for everyone to see.

“What is the title of the table?” asked Mrs. Mercado.
“‘Favorite Animal’,” replied John smartly.
“What are the choices presented in the table?” the teacher
asked further.
“Favorite animals such as rabbit, dog, cat, bird, fish, and
turtle,” replied Cely.
“Now, you can take the survey. Write your classmates’ name
in the table to show their choices,” guided the teacher.
