Solves routine and non-routine problems involving circumference of a circle.

3. Presenting examples/instances of the new lesson

Present the problem.

Mrs. Nicolas planted dwarf santan around her circular flower garden which has a diameter of 8 metres. How many metres did she plant with

dwarf santan?

Ask:

What did Mrs. Nicolas planted in her garden?

What is the shape of the garden of Mrs. Nicolas?

How will you solve the problem?

Let the pupils sing an action song about circles like.

        Small circle, small circle, big circle

        Small circle, small circle, big circle

        There’s mama, there’s papa waiving at me

        There’s mama, there’s papa smiling at me

        6 x 6 is 36, 6 x 6 is 36

        6 x 6, 6 x 6, small pig

4. Discussing new concepts and practicing new skills #1

Group the pupils in 5 working teams. Ask the teams to work together in looking         for the solution to the problem.

Expected answers

Solution 1:

To find the circumference, multiply the diameter by 3.14

d  =  8 m

C  =  π  x  d

=  3.14  x  8 m

=  25.12 m planted with dwarf santan

Solution 2:

If radius is given use this formula, C = 2πr

Given: 4 metres radius

C  =  (2 x 3.14) 4

   =  6.28 x 4

  =  25.12 m

Alice is making a circular table cloth. It has a diameter of 2 meters. How many meters of lace are needed to decorate the sides of the table cloth?

Know:         What is asked?

                What are the given?

        Decide: What will you do to answer the problem?

        C=

        Solve: Show the solution

                = 3.14 x 2

                = 6.28 meters

Check: How will you check it?

5. Discussing new concepts and practicing new skills #2

How did you find the activity?

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

Discuss with the pupils the formula in getting the circumference of a circle.

Group Work- Give each group an activity card and different sizes of circles.

a. Find the center of the circle.

b. Measure the diameter of the circle.

c. Find the radius of the given circle.

d. Solve for the circumference.

e. Report to the class how you found the answer.

6. Developing mastery

(Leads to Formative Assessment 3)

Discuss the presentation under Explore and Discover on page _____ of LM         Math Grade 5. Then, give the following activities:

Ask the pupils to answer the activity under the Get Moving on page ____,                 LM         Math Grade 5.

Analyze and solve for the answer. (To be done in pair)

1. Mr. Reyes is laying out a circular playground. Its radius is 50 meters. What is its circumference?

2. What is the circumference of the circle if the diameter is 24 meters?

3. A bicycle tire has a radius of 30 cm. Find the distance around the tire.        

7. Finding practical applications of concepts and skills in daily living

Ask them also to answer the activity under Keep Moving on page ___, LM Math Grade 5.

Group Activity

8. Making generalizations and abstractions about the lesson

Lead the pupils to give the following generalization by asking: “What is the formula in finding the circumference of a circle?”

To find the circumference of the circle, use the formula:

C  =  2πr        or        

C  =  πd

How do we solve problems on circumference?

        In solving problems involving circumference measure, know the diameter/radius and the formula,

C=         or         C=

9. Evaluating learning

Find the circumference of the circle with the following radius or diameter.

1)  r  =  11 m                

4)  r  =  9.5 m

2)  d  =  2 cm                

5)  d  =  16 cm

3)  d  = 20 m

Read, analyze and solve.

1. Lorna’s circular garden is 5 meters in diameter. How many meters of wire are needed to put a fence around it?

2. The diameter of a tricycle tire is 60 cm. How far will the tire go in one rotation?

3. Find the circumference of a circle with a diameter of 21 meters.

4. Your friend is finding the circumference of a circle with a radius of 25 cm. help him solve for the answer.

5. If the circumference of a circle is 250 meters, how long is its radius?
