4. Motivation
How many of you are observant with the day’s
temperature?
Why does a weatherman inform us about temperature
readings?
Why do you think there is a need to check the day’s
temperature from time to time?

6. Ask:
1.What are the parts of a line graph?
2.Looking at the data, can you
interpret what is presented by the
graph? How?
3.How does a line graph help in data
presentation?
4.Is it important to have an accurate
data? Why?
Present a line graph with complete parts and let the pupil interpret the data.
7. Group the pupils into four.
Give activity sheets involving line graph to each group
for interpretation.
Ask each group to work together in interpreting the
data on the graph. Once finished, the assign member
will post their work on the board and discuss their
answer.

9. A line graph is also known as a line chart. It has an X-
axis (horizontal) and a Y- axis (vertical). It is a graph that
was points and lines to display values over a period of time.
Five parts of the line graph must be present for the
graph to be complete.

10. a line graph is simple and easy to understand.
It is used to track changes over short and long
periods of time.
It is better to use a line graph when there are
smaller changes in data.
When comparing a lot of data all at once, a line
graph is very effective.
When to use a line graph?

15. •A line graph has a title, scale, labels, points, and line•
Changes in the data presented are easily seen on a line
graph.
•To read and interpret the data presented in a line graph, we
usually compare the data in terms of size and amount.
What are the parts of a line graph? Why?
Generalization
16. Why it is useful?
Line graph are used to track changes over
short and long periods of time.
How do we interpret data presented on a line graph?
To read and interpret the data presented in
a line graph, we usually compare the data
in terms of size and amount
17. The horizontal scale across the bottom and the
vertical scale along the side tell us how much
or how many. The points or dots on the graph
represents the X,Y, coordinates or ordered
pairs. The line segments connecting the points
give estimated values between the points.
18. a. What is the title of the graph?
b. How many mangoes were
harvested for the first two weeks?
c. In what week was there the greatest
amount of harvest?
d. What is the least amount of mango
harvested?
e. What is the total amount of harvest
for six weeks?
Study the line graph, and then answer the question below.
