The document details a classroom observation focused on interpreting line graphs in a mathematics lesson for grade 5. It presents a scenario where a student, James, tracks vegetable sales through a line graph, asking various questions related to the data. Additionally, it includes a framework for students to analyze another line graph related to burger sales, reinforcing their understanding of graph interpretation.

Line Graphs

6.  James, a Grade 5 pupil, developed a hobby of
planting different vegetables in their farm during
this pandemic. He helped his father plant squash,
egg plants, beans, and bitter gourd in their small
farm. Now, its harvest season and they sell their
products in the market. On Monday, they earned
₱500.00, on Tuesday their sales is ₱400.00, while
on Wednesday, they had an earning of ₱600.00.
On Thursday, they were able to sell their veggies
for ₱500.00. Friday was their lucky day for they
sold all their products for ₱900.00. They made a
line graph to monitor their sales.

8. What is the line graph all
about?
What data can be found in x-
axis? y-axis?
What is the scale used in the
y-axis?
How much did they earn on
Monday? Wednesday? Friday

9.  What day has the highest sale?
How much? Lowest? How
much?
 What days have the same
amount of sales?
 How much more earnings they
got on Friday than on Tuesday?
 How much did they earn in 5
days?

10.  Determine the given data in x and y
axes
 Determine the range of the graph
 Base your answers from the data
presented in the graph
 In a line graph, a line that goes up
means an increase in value, while a
line that goes down from its
previous point means a decrease in
value.
