IV. PROCEDURES

A. Reviewing previous lesson or presenting the new lesson.

Distribute cut outs to pupils. Let the pupils tell the number of square units the figure has

Show grids to pupils with different figures.

Let them estimate the area of those figures.

Let the pupils draw their grids with the corresponding figures inside.

Let them also count and estimate the area of the figure drawn on their grids.

Estimating the area of the figures parallelograms, triangles, and trapezoids.

What are the steps in solving problems?

B. Establishing a purpose for the lesson

 Motivation: Can you estimate the area of a figure?

How many square units cover the figures?

Let the pupils count the square units the triangle and the parallelogram occupy.

Conduct a drill on performing the basic operations of whole numbers. Solve for n.

9  x  8  =  n

12  x  16  = n

( 15  x  8  )  divided by 2  = n

( 16 + 4)    =  n

        2

Show cutouts of a trapezoid.

Estimate the area.

 Show cut outs of a triangle. Estimate the area.

Estimate the formula

Present the situation under explore and Discover on LM pp. 215

Complete the information for that object by making estimates and the actual area.

  Let the pupils visualize and solve the given problem.

   A triangular landscape has a base of 24 meters and a height of 12 meters. Find its area?

What is the first thing we will do?

After visualizing the problem, what step is next?

C. Presenting Examples/ instances of the new lesson

Present the situation to the class.

Estimate the area of the following figures.

 Consider yourself a designer of furniture and fixtures for homes. How would your knowledge of area of geometric figures you have studied help you designing new products?

Present grids to pupils. Explain about how to estimate the area of the figures trapezoid, parallelograms and triangles.

   Let the pupils do the following on Get Moving on LM p. 216   1 and 2

   Let the pupils solve problem number 3 in Get Moving on LM p. 216

D. Discussing new concepts and practicing new skills #1

Divide the class into 5 groups. Give each group a grid with figures.

What helped you estimate the area of the figure?

How did you estimate the area of each figure?

What helped you estimate the area of the figure?

How did you estimate the area of each figure?

Discuss about how to solve routine and non-routine problems.

Discuss how to solve routine and non-routine word problems.

E. Discussing new concepts and practicing new skills #2

Guided Practice

 Let the pupils answer Get Moving on LM p 213

Guided Practice

Estimate the figure by group.

Group I

Group II

Estimate the area of trapezoid.

Group III-Estimate the area of triangle.

Guided Practice

By group

Guided Practice

Use the 4-way steps.

1.A residential lot has the shape of a parallelogram. Its base measures 20 meters. The distance between the 2 parallel sides is 8 meters. What is the area of the lot?

Guided Practice

Solve:

                  34 cm

                                        24 cm

The garden has a length of 34 cm and a width of 24 cm. What is its area?

F. Developing mastery

H. Making generalizations and abstractions about the lesson

To estimate the area of a parallelogram, triangle, or a trapezoid:

*Count the number of square units that are completely inside the figure

*When only part of the square is included in the figure, put it together with those partly square in the figure to form a whole square.
