Introduction
George found all of his markers and put them in one box.
He recorded the number of markers in this table.
4 red
6 blue
3 green
One way George can show the number of markers he has is to make a bar graph. A bar graph must have the following information:
a
title
with capital letters
evenly spaced
lines
to show the number of items
labels
for the lines, the left side and the bottom
names
or pictures for what each bar represents
Identify this information on the empty bar graph.
The numbers
0 through 6
are labels for the number of markers.
The label on the left,
Number of Each Marker
, tells what the numbers mean.
The words
Red, Blue
and
Green
are labeled on the bottom.
The label
Colors
identifies the category of information along the bottom of the graph.
The
title
of this bar graph is in
red
. It tells what the graph is about.
A bar graph also has bars to show the number of items. To make the bars, shade one block for each marker.
4 blocks represent 4 red markers
6 blocks represent 6 blue markers
3 blocks represent 3 green markers
The bar graph shows the number of each color of George's markers.
Examples
The bar graph shows the bugs the first grade science club collected.
1.
Use the bar graph to count how many ladybugs were collected.
The bar graph has five blocks shaded above the ladybug.
Each block stands for one ladybug.
The science club collected 5 ladybugs.
2.
Look at the bar graph. How many beetles were collected?
The three blocks above the picture of the beetle are shaded blue.
Each shaded block stands for one beetle.
The science club collected 3 beetles.
Sheri wants to make a bar graph showing the coins she found in her pocket.
3.
The labels for Sheri's bar graph are numbered 1, 2, and 3. What words should be in the labeled boxes?
The Box 1 label should say "Sheri's Coins".
The Box 2 label should say "Number of Coins".
The Box 3 label should say "Types of Coins".
4.
Shade the blocks in the graph above to show the number of each coin.
