The Strategic Intervention Material was designed to give the learners a wide understanding on the different concepts related to temperature.
The result of the 2021-2022 Diagnostic Test in Mathematics 5 conducted last September 18, 2021 in Cataggaman Elementary School in the Division of Tuguegarao City showed that the performance level of the Grade V pupils in solving routine and non – routine problems involving temperature in real - life situations. (M5ME-IVf-85) was very low. Same result was also shown in the Fourth Quarter Summative Test in Mathematics V for the School Year 2020 -2021. It was also suggested in the COT – RPMS Observation Note Form of the school head during her observation the need to prepare a Strategic Intervention Material for the said competency. Furthermore, during this time of pandemic, we heard feedbacks from parents that the need for supplementary materials to be utilized by the pupils, aside from the available Self Learning Modules and Learning Activity Sheets, are supreme necessary to improve this learning competency.
There should be mastery of pupils in identifying the parts of thermometer and reading temperatures shown in the thermometer so that they can solve routine and non - routine problems involving temperature.

GUIDE CARD
The hottest man-made temperature ever recorded is 7.2 trillion degrees Fahrenheit, or about four billion degrees Celsius. It’s about 250,000 times hotter than the temperature at the core of the sun. The extreme recording was made at the Brookhaven Natural Laboratory in New York.
Main Task:
In this lesson, you will learn the concept of solving routine and non - routine problems involving temperature in real life situations.
For you to understand the lesson better, you are going to do series of activities. Here is the list of activities that you are going to perform:
SUBTASKS:
Activity 1 - you will identify the parts of thermometer and its functions.
Activity 2 - you will convert temperature readings from ˚C to ˚F and
vice versa.
Activity 3 - you will estimate temperature.
Activity 4 - you will solve routine and non – routine problems involving temperature in real life situations.

ACTIVITY CARD 1
Temperature is measured using a thermometer. The English unit of temperature is degrees Fahrenheit (˚F), while the metric unit of temperature is degrees Celsius (˚C.)
Parts of a Thermometer
1. Get your thermometer at home.
2. Identify its parts.
3. Get the temperature of each member of the family and
record it in degrees Celsius (˚C.)
4. After doing the activity answer the following questions:
a. What is a thermometer?
b. What are the parts of a thermometer and its functions?
c. How do you measure temperature?
Were you able to answer all the questions correctly? If you did you can now proceed to the next activity.

1.) ˚ F ˚C 2.) ˚F ˚C 3.) ˚F ˚C
4.) ˚ F ˚C 5.)˚F ˚C
The following formulas are used to change temperature readings from ˚C to ˚ F and vice versa.
˚ F = (˚C x 9/5) + 32
˚ C = (˚ F – 32 ) x 5/9
TITLE:
“Converting temperature readings”
ACTIVITY CARD 2
What you need to know…
A. Write the temperature reading in ˚ C and convert it to ˚ F.
B. Write the temperature readings in ˚ F and convert it to ˚ C.
What is your score? Were you able to do it? If you did, proceed to the next activity.

Anders Celsius developed thermometer using the ˚C while Gabriel Fahrenheit invented the thermometer using the ˚F. The normal boiling point of water is 100˚C or 212˚F. The normal freezing point of water is 0˚C or 32˚F . The normal body temperature is 37˚C or 98.6˚F.
TITLE: “Estimating temperature.”

In solving problems involving body temperature, you need to understand the problem, plan what to do, solve for the answer and check.
TITLE:
“ Solving routine and non - routine problems involving temperature in real life situations.”
1. The water in a pot boiled at 100 ˚C. After a while, its
temperature dropped to 35 ˚C. What is the difference
in temperature in ˚ F?
2. Denver had fever and his temperature rose to 40 ˚C.
After 4 hours, his body temperature became 104 ˚ F.
Did Denver’s temperature rise or fall? By how many
degrees Celsius?
3. The normal body temperature is 37 ˚C. If Sandro’s
body temperature increases by 2.5 ˚C, what is his
temperature in ˚ F?
4. Ysa baked a cake at 350 ˚F heat. This is equivalent to
how many degrees Celsius?
5 A farmer started working on the farm. He recorded
that at 7:00 am, the temperature was 12˚C. The
temperature rose by 30˚C at 12:30 p.m. but dropped
by 15˚C at 2:00p.m. When he got off from work at
5:30p.m.,the temperature dropped by 5 ˚C. What
was the temperature at 5:30 p.m.?
