Review

A.Checking of Assignment

B.Identify the parts of a circle

C.Review the steps in solving word problems.

1.Drill

Have a drill on the multiplication facts

Review

Have a review on solving the area of a circle. Let the pupils do the following

  1. Establishing a purpose for the lesson

3.Motivation

Name any round objects inside the classroom or any round object that you brought. Show the diameter and the radius.

3.Motivation

Let the pupils find any circular objects inside the classroom. Ask them to record the area of each object.

  1. Presenting examples/instances of the new lesson

1.Presentation

Present the situation under Explore and Discover on page ___, LM Math Grade 5. Discuss the situation with the class.

1.Presentation

Let the pupils present their answers. Ask them how they got the area.

  1. Discussing new concepts and practicing new skills #1

Performing the Activities

Divide the class into four groups and instruct them to bring out the materials that they brought like paper plate, ice cream cup cover or any round object. Let the pupils measure the diameter. Divide the diameter by 2 to get the radius. Tell the pupils that the value of π is approximately 3.14 and that the formula in finding the area of a circle is A= πr^2

        Solve for the area of the circle. Ask the leader to report their answers.

2.        Performing the Activities

Divide the class into four groups. Let each group discuss how will they make a problem based on the given situations. The groups 1 and 2 will discuss situation 1, while groups 3 and 4 will focus on Situation 2.

Situation 1:

        Inside the classroom, find any circular objects, create a problem involving area of a circle. Use a ruler/meter stick as the measuring tool.

Situation 2:

        In the school campus, find any circular objects, create a problem involving area of a circle use a ruler/meter stick as the measuring tool.

  1. Discussing new concepts and practicing new skills #2

3.Processing the Activities

After the presentation of the groups, ask:

•How did you find the activity?

•How did you go about the task?

•What did you do with the objects before getting their areas?

•How did you solve the area?

3.        Processing the Activities

After the activities have been done, let the groups post their formulated problems in each of the situations given and let them do the tasks below.

1.        Read the problem and ask the class to solve the problem.

2.        Illustrate and solve the problem with the solution.

  1. Developing mastery

(Leads to Formative Assessment 3)

Reinforcing the Concept and Skill

    a. Class Activity

         Say: Let us solve more problems. Ask pupils to do the exercises by pairs under Get Moving on pages _____ of LM Math 5. Check the pupils’ answers.

    b. Group Activity

         Divide the class in four groups. Let them choose a leader and a secretary. Give each group an activity card with problems written on it. Then each group will post their work on the board. The leader will explain their answers and solutions.

Activity Card 1

Problem 1: A circular basement has a radius of 6 m. If it will cost ₱471 per square meter to pave the basement with bricks, what will the total cost be?

Activity Card 1

Problem 2: Lyn wants to refinish a circular table that is 2.4 meters in diameter. If the refinishing costs ₱255 per square meter, how much will she spend?

        Activity Card 3

              Problem 3: Carlo has a circular window with an area of approximately 4069.44 〖cm〗^2. Find the radius of the window          

           Activity Card 4

Problem 4: What is the area of a circular garden whose diameter is 15 meters?

Reinforcing the Concept and Skill

    a. Class Activity

         A. Ask the pupils to do the exercises in the Get Moving and Keep  

              Moving pages_____ and ____, LM Math Grade 5.

           B. Ask the pupils to work by groups. Check the pupils answers

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

Applying to New and Other Situations

            a. Group Activity

              Divide the class in two groups. Give each group an activity card with problems written on it. Let each group post their work on the board. The leader will report to the class the answer and solution of the problem.

  1. Making generalizations and abstractions about the lesson

Lead the pupils generalize the following.    

   Steps in solving problems involving the area of a circle

The formula in finding the area of a circle

A = πr^2

Lead the pupils to give the generalization by asking: How did you create problems involving area of a circle?  

 Steps in Creating Problems

1.Familiarize yourself with the mathematical concepts. Think of the application to everyday life situations.

2.Think of the type of the problem you want to make and the formula to be used.

3.Read and study more on math problems. Study the solutions.

4.Make your own styles/strategies to justify the solutions.
