PICTOGRAPHS
Calling all
students!!
Let’s learn
about
PICTOGRAPHS!
PICTOGRAPHS
A Pictograph is a graph
that uses pictures or symbols
to show and compare data.
A Key is the part of a
pictograph that tells what
quantity each symbol stands
for.
There are many
animals that are
in trouble. We are
called endangered
animals. I will be
using pictographs
to show you how
serious our
problem is!!
There are only 3,500 Florida
Manatees. The major cause of death is
accidents with boats.
Only 2,500 Black Rhinos
are alive today.
At the turn of the century, there were around
45,000 Bengal tigers in India. At present
there are fewer than 2,500 Bengal tigers
living in the wild.
There are 4,000 Eastern Imperial Eagles
today.
O.K., now let’s
put all of this
data about my
endangered
friends in a
pictograph!!
Here we go………..
