2. Establishing a purpose for the lesson

3.Motivation

        Mother wants to find out if her son has a fever.

        What is the best thing mother can use to find the body temperature of her sick son?

Motivation

  How do you know if you have a fever?

   One has a fever if one’s body temperature is above the normal body         temperature. The normal body temperature is 37◦C?

  What will you do if one of the members of your family has a fever

3.Motivation

Show 2 glasses of water, one has cold water and the other has hot water.

Let the pupils get the actual temperature of the 2 glasses of water. Record the results.

Ask: Which of 2 has a higher temperature? lower temperature?

  How much higher is the temperature of one glass than the other?

Valuing: Getting the actual temperature of one’s body is important.

Why should we read the thermometer with accuracy

3. Presenting examples/instances of the new lesson

1.Presentation

        Present a model of an improvised thermometer. It has a movable red ribbon which resembles the mercury in an actual thermometer.

             Ask:

What does the red ribbon represents?

Give each group an improvised thermometer, announce the temperature  readings,

 The pupils will reflect it in their thermometer model.

Check if the temperature reading each group is showing is correct

1.        Presentation

     Present the situation to the class.

       Mother wants to find out if her son Rommel has fever. She got her thermometer and found out that the mercury level in the thermometer is at 38.5◦C, If the normal body temperature is 37.5◦C, how much higher is her son’s temperature than the normal body temperature?

Ask: What did Mother wants to find out?

What did she do?

What kind of mother is she?

Is your mother as kind as Rommel’s mother?

Why is it important to know one’s temperature?

Ask:         What are the given facts?

 What is asked in the problem?

What operation are you going to use?

Do we need the exact/ actual answer in the problem?

What word/s suggests that we need only to estimate?

1.        Presentation

                Present a problem opener.

                                        Problem A

     The weather report in one newspaper predicted the lowest temperature for the day to be 24◦C and the highest at 32◦C. What was the difference in the predicted temperatures for that day?

Problem B

     Marina has a fever. At 12 noon, her temperature increased by 1.8◦C from her temperature at 7 A.M. Then her temperature went down by 1,3◦C at 5 P.M. At 11 P.M., her temperature rose again by 1.1 ◦C. If her temperature at 11 P.M. was 39.7◦C, what was her temperature at 7 A.M.?

Ask: How are you going to solve each problem

4. Discussing new concepts and practicing new skills #1

2.Performing the Activities

Group Activity

        Divide the class into four groups. Distribute activity sheets in each group.

Provide group 1 with digital thermometer, Group 2 with set of pictures showing temperature readings and Group 3 using pictorials, Group 4 with alcohol thermometer.

Group 1 - Using digital thermometer

Group 2 - Using pictures of temperature readings

Group 3 - Using pictorials

Group 4 – Using alcohol thermometer

Let them discuss how they read and measure the temperature

Group 1- Measure and read the pupils body temperature by putting the digital thermometer under their armpits. Record and compare the results with the other pupils.

Group 2 - Read and record each thermometer reading

Group 3 - Give pictures and write if it is HOT or COLD

-Picture of Baguio city

-Picture of a dessert

-Picture of a glass of cold glass of water

-Picture of cup of coffee

Group 4 -  Give 2 glasses of water, one has cold water and the other has hot                               water, using alcohol thermometer measure the temperature of each    glasses. Read and record.

2.Performing the Activities

Say: Estimating is an educated guess. There are times when an estimate is  

needed and not the actual one.

Say: Let us solve and analyze the solution to the problem.

38.5◦C                    39◦C                 - 37.5◦C                   -38◦C

                    1◦C estimated difference

So, 1◦C is much higher is her son’s temperature than the normal body temperature.

Performing the Activity

        Group the pupils into four learning teams. Ask the groups to work together in

Solve for the answer to each problem. Give the learning teams enough time to do the task.

Solution to Problem B : Using the 4- Step Plan

Understand : Know what is asked : What was Marina’s temperature at 7 A.M.?

Know the given facts : At 12 noon, her temperature increased by 1.8◦C from her temperature at 7. A.M .Then it went down by 1.3◦C at 5 P.M.

                                 The temperature at 11 P.M. was 39.7◦C.

Plan: Determine the operation to be used: Addition and subtraction

             Write the number sentence: 39.7◦C - (1.8◦C-1.3◦C+1.1◦C) = N

Solve: Show your solution (Illustrate the problem by using a diagram)

        39.7◦C - (1.8◦C-1.3◦C+1.1◦C) =38.1◦C Marina’s temperature at 7 A.M.

Check and Look back:                 38.1◦C + 1.8◦C = 39.9◦C

                                        39.9◦C -  1.3◦C = 38.6◦C

                                        38.6◦C +  1.1◦C= 39.7◦C

5. Discussing new concepts and practicing new skills #2

3.Processing the Activities

Ask: How did you find the activity? How were you able to read and measure the  temperature? Discuss. Emphasize that ◦C is read as “degree Celsius” it is used  to express temperature. Discuss the difference between an alcohol and a digital

thermometer.

Processing the Activities

Ask:         How is estimation done in the solution we have in the problem?

        What was done first to the numbers?

        Then, what was cancelled in the rounded numbers?

        Then what was done next?

Say :         Now, let us compare the actual answer to the estimated one.

Ask:         Are the difference the same or different?

        How near or far is the estimated answer to the actual one?

        What will you do if the estimated answer is too large or small compared to

        the actual one?

Say:         There are times that the estimated answer is too long or small if we

        round both the numbers to the highest place value. One way to make our    

            estimated answer reasonable or close to the exact answer is by using

        compatible numbers.

3.Processing the Activities

After all groups have presented their output, ask these questions.

•How did you find the activity?

•How were you able to find the answer to the problem?

•In how many ways were you able to arrive at the answer?

   Discuss with the pupils the ways on how they were able to solve for the answer to

 The problems. ( Use the 4- step plan and illustrating a diagram)

   Ask: Are there was by which you can solve the given problems?

The first problem is an example of a routine problem. Routine problem solving concerns solving problems that are useful for daily living ( in the present or future).

The second problem is an example of a non routine problem. Non routine problem solving is mostly concerned with developing pupil’s mathematical reasoning  power and fostering the understanding that mathematics is a creative endeavor.                         This kind of problem helps the teacher to motivate and challenge their pupils.           Some strategies used in this kinds of problem are Guess and Check, Drawing         Diagram,

 Using patterns, Working Backwards.

8. Making generalizations and abstractions about the lesson

5.Summarizing the Lesson

Ask the following questions:

What is a temperature?

How can we measure temperature?

What are the parts of a thermometer?

What is the metric unit for measuring temperature?

•Temperature is the measure of hotness or coldness of an object.

•We can measure temperature by using thermometer.

•The parts of a thermometer are: mercury, glass tube, glass bulb, and scale.

•The commonly used unit to measure temperature is degree Celsius ( ◦C ).

5.        Summarizing the Lesson

Lead the pupils to generalize as follows.

        To estimate temperature, round the number to the highest place value and use compatible numbers for the number to be estimated. This will make your estimated temperature reasonable.
