III. PROCEDURES

(These steps should be done across the week. Spread out the activities appropriately so that students will learn well. Always be guided by demonstration of learning by the students which you can infer from formative assessment activities. Sustain learning systematically by providing students with multiple ways to learn new things, practice their learning, question their learning processes, and draw conclusions about what they learners in relation to their life experiences and previous knowledge. Indicate the time allotment for each step.)

A. Reviewing the previous lesson or presenting the new lesson

Have a review on solving for the perimeter and area of a triangle, a parallelogram, and a trapezoid. Let the pupils do the following:

  1.                              2.

Ask: What can you say about the block? What are the dimensions?

C. Presenting examples/instances of the new lesson

Let the pupils present the figures and discuss how the area and perimeter are obtained. Ask them to give the different ways in finding the area and perimeter.

Present this situation to the class. Let the pupils read and understand the situation.

Charo has a transparent rectangular container, measuring 10 cm by 4 cm by 3 cm. What is the volume?

Ask: Who has a transparent rectangular container? What is the length? Height? Width? What does the problem ask for? How will you solve the volume of the rectangular prism?

D. Discussing new concepts and practicing new skills #1

Group Work Activity

Divide the class into three groups. Let each group discuss how they will make a problem based on the given situation.

  1. Inside the classroom, create a problem involving perimeter and area. Use the meter stick/ruler as the measuring tool.
  2. In the school campus, create a problem involving perimeter and area. Use the meter stick/ruler as the measuring tool.

After the activities have been done, let the groups post their formulated their 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.

Guide the pupils in creating a problem about the situation.

Group Activity

Divide the class into 3 groups. Let each group solve and answer the problem created.

Ask: Which box has the greater volume? Let them compare the contents of each box.

Ask the pupils why the boxes do not have the same number of materials or objects.

Ask them why there are gaps or empty spaces within the boxes. Explain the meaning of volume and non-standard units.

Show and discuss how to find the volume using different methods.

-Compare the volume using the non-standard units and the volume using the standard units.

-What is accurate in finding the volume?

Discuss the presentation under Explore and Discover on p. 229, LM.
