This document outlines a lesson plan on bar graphs for grade 4 students. The plan has the objectives of teaching students to identify parts of a bar graph, read and interpret data from a bar graph, construct a bar graph, and understand the importance of bar graphs. The lesson includes activities like group work to organize shapes into a bar graph, analyzing sample bar graphs, and applying understanding to answer questions from a bar graph. The goal is for students to understand how to properly construct and interpret information from bar graphs.

Learning Task 4– Motivation
I want you to take a look of this illustration.
What arethe information given in illustration?
What do we call this illustration?
Do you know how to use it?
Take a look of this.
Are the shapes organized?
Do you want us to organize it?
Shapes distribution, no. of shapes, and shapes.
Chart.
No.
No they aren’t.
Yes we do.

4. 4
Learning Task 4 - Activity
Now we will have a group activity.
I will group you into three.
Each group, I want you to choose your leader.
This is the instruction.
Group 1 will get the stars from the board.
Group 2 will get the circle and
Group 3 will get the square.
Count the number of each shape and shade the
numbers of each shape on the chart.
Is it clear?
I will give you five minutes to do this.
But before that what are the standards to be
followed in doing group activity?
Alright let’s start.
Learning Task 5 - Analysis
Let’s find out if your answer is correct.
Group 1, how many stars do you have?
Post your shapes on the board.
Group 2, How many circles do you have?
Yes it is.
 Follow the instruction.
 Follow the time allotment.
 Work quietly.
 Be cooperative

5. 5
Group 3, How many squares do you have?
Is the chart correct?
So, are the shapes on the board organized?
Therefore, what is the use of graph?
Very good.
What kind of graph do we formed?
Very good!
And what is the bar graph?
Do you know what the parts of bar graph are?
Let us sing once again the song on the board.
Legend, title, legend, title,
Label, label.
Vertical, horizontal, vertical, horizontal
Making graph, making graph.
Those are the parts of a bar graph.
What do you think is the legend?
Why did you say so?
Very good.
Another example:
(Pupils post their shapes on the board.)
8
(Pupils post their shapes on the board.)
Yes it is.
Yes they are.
We used it to organize something.
Bar Graph.
A bar graph uses bars of different heights or
lengths to show and compare information.
No we don’t.
Legend, title, legend, title,
Label, label.
Vertical, horizontal, vertical, horizontal
Making graph, making graph
The shapes.
Because it is the one that need to organize.

6. 6
Carla made a survey on the number of the books
read by her friends during the year. She organized
the data in a table. What information does the
table show?

Do you know how to organize it using a bar
graph?
These are the step to be followed in constructing
a bar graph.
Kindly read the first one.
Step 2.
Step 3.
Step 4.
Step 5.
What are we call this kind of bar graph?
Is the information organized?
How many books did Mark read?
How about Kyla?
Robin?
Anne?
Who read the same number of books?
Who read most?
No we don’t.
Step 1: Find the greatest number in the data.
Step 2: Make a scale from 0 to the greatest
number.
Step 3: Label the horizontal and vertical axes.
Step4: Draw a bar to represent each data.
Step 5: Writea title for the Graph.
Horizontal bar graph.
Yes it is.

Learning Task 7 – Application
Use the graph to answer the following
questions.
1. What is being compared in a graph?
2. How many pupils prefer to watch
cartoons?
Number of Books Read
Names and no. of books.
No. of books read by Carla’s friends.
Graph is use to organize something?
A bar graph uses bars of different heights or
lengths to show and compare information.
Legend, Title and label.
Vertical and horizontal bar graph.
Step 1: Find the greatest number in the data.
Step 2: Make a scale from 0 to the greatest
number.
Step 3: Legend the horizontal and vertical axes.
Step4: Draw a bar to represent each data.
Step 5: Write a title for the Graph.
None at all.
