### Final Project in ICT

Submitted by: Lorelyn M. Ramos

Overview

Goal of the lessons : To find the area of a square and rectangle.

Pedagogical approach : Constructivism

Skills/knowledge :

• Identify rectangle and square in the classroom.
• Relate the characteristics of different figures.
• Understand the concept of area .
• Derive the formula in finding the area of rectangle and square.
• Find the area of a figure in square units.
• Solve word problems.

Kinds of technology tools:

• 1 Laptop with internet connection
• 1 LCD projection system
• Power Point Presentation
• You Tube
• Individual and group activity sheets
• Other manipulative objects such as Geo board and paper folding
Objectives

1. Identify square and rectangle in the classroom.

2. Relate the characteristics of different figureswith

the use of tangram.

3. Visualized and understand the concept of area.

4. Derive the formula in finding the area of square

and rectangle.

5. Find the area of a figure in square units.

6. Solve word problems.

Subject Matter

Finding the Area of a

Square and Rectangle

Materials
• Laptop with internet connection
• LCD projection system
• Power Point Presentation
• You Tube
• Individual and group activity sheets
• Manipulative such as paper and tangram
• Geo board
Motivation

This is a black board.

What is the shape of a black board?

Can you give me more example an a rectangle?

(door, window, table etc.)

This is a picture frame.

What is the shape of a picture frame?

Can you give me more example an a square?

(frame, ceiling, chart, etc.)

Motivation

What have you noticed with a rectangle?

- It has two pairs of equal sides

What have you noticed with a square?

- It has four equal sides

Compare a rectangle and a square.

- Rectangle has two pairs of equal sides while

a square has four equal sides

Presentation

Solve the following using a geo board.

1. a. Make a 4 x 4 square in a geo board.

b. Let the pupils count the number of

square inside the square.

(16 square units)

• a. Make a 5 x 6 rectangle in a geo board.

b. Let the pupils count the number of

square inside a rectangle.

(30 square units)

Activity

Constructing Your Own Set of Tangrams

Materials :

a rectangular piece of paper suitable for folding

a pair of scissors

a ruler (optional)

Activities :

A complete set of tangrams consists of seven pieces:

a small squaretwo small congruent trianglestwo large congruent trianglesa medium-size trianglea parallelogram

You can make your own set of tangrams from a single piece of paper.

Activity

1. Fold a rectangular piece of paper 2. Cut the square into two triangles.

so that a square is formed.

Cut off the extra flap.

3. Take one triangle and fold it in half.

Cut the triangle along the fold

into two smaller triangles.

Activity

4. Take the other triangle and 5. Fold the trapezoid in half and fold again.

crease it in the middle. Cut along both folds.

Fold the corner of the triangle

opposite the crease and cut.

Activity

6. Fold the remaining small trapezoid and cut it in two.

Tangrams are a puzzle that help develop spatial-visualization skills,

but they may also be used to introduce or reinforce geometrical

concepts such as congruency, similarity, symmetry, and so forth.

This unit for grades 4 through 6 uses tangrams to compute the

area of polygons  without formulas. In the process of doing so,

the terms congruent  and similar  are introduced.

Group Activity

Tangram Activities

Objectives

• a better understanding of area without formulasthe ability to compute the area of polygons by decompositiona familiarity with the names of certain polygons
• (e.g., rectangle, trapezoid, and pentagon)
• the meaning of the term similarto develop geometric intuition

Materials

• a package of tangrams for each studenta student notebooka sharp pencila ruleran overhead projector
Group Activity

Primary activities

• The student can compute the area of any  polygon constructed from tangrams. Make a square with the medium-size triangle and the two small congruent triangles. What is the area of this square? How do you know? Sketch the square in your notebook and record its area.

2. Make a rectangle with the parallelogram and the two small congruent triangles. What is the area of this rectangle? How do you know? Sketch the rectangle in your notebook and record its area.

Evaluation

Solve the following word problem:

A square lot measure 14 meters in one side.

What is the area of the lot?

A rectangular garden has a width of 20 meters and a length of 35 meters. What is the area of the garden?

A quadrangle has a perimeter of 80 meters. If the shorter side of the quadrangle measures 20 meters. What is the area of the quadrangle?

A floor area measures 15 meters by 12 meters. How many tiles that measures 1 meter by 1 meter is needed to cover the whole floor area?

A rectangular measures 18 meters by 9 meters.

What is the area?
