A SAMPLE LESSON PLAN IN MATHEMATICS GRADE FOUR USING BLOCK MODEL

APPROACH

I. Objective

Solves word problem involving addition in similar fraction

II. Subject Matter

A. Solving word problem involving addition in similar fraction

B. B. BEC-PELC, Mathematics 4, Textbook, pp. 105-106

C. Textbooks, flashcards, charts, show-me-board, cut-out objects

III. Learning Procedure

A. Drill

Identify whether the given fraction is proper or similar fraction

1. 5/4

2. 1/5

3. 6/8

B. Review

Tell whether each given example is similar or dissimilar fraction

1. 2/4, 1/2, 1/3

2. 3/5, 1/5, 2/5

3. 1/8, 3/8, 5/8

C. Motivation

*(Hanapin mo ang kasama ko)

*Finding the pair of object in order to form a similar fraction and after that adding

all the newly found objects by using their corresponding fraction as written on

the object.

B. 1. Presentation

Amy and Iris were invited in a party. Amy eats 2/4 of the whole cake, and Iris

eats twice as much Amy has eaten. How many parts of the cake they have eaten

in all?

Amy- 

2/4

Iris- 

4/4

Now, we will use shaded and not shaded blocks to represent the parts of the cake that

they have eaten in all. So, out of six parts of the cake, Amy has eaten two parts of it,

while Iris has eaten four parts of it. Thus, the shaded blocks represent the total parts of

the cake they have eaten in all.

Therefore; 2/4+4/4= 6/4 or 1 and 2/4

6/4- total parts of the cake did Amy and Iris have eaten in all.

2. How many parts of the cake did Amy and Iris eat in all?

3. In adding similar fraction, simply add the numerators and copy the denominators of

each fraction, reduce it to the lowest term if necessary.

4. How will you add similar fractions?

5. Find the sum

Ariel and Allan were given a gift by their grandma. Ariel received ½ amount of the gift

as much as Allan received. What is the total amount of the gift did they receive in all?

IV. Evaluation

Solve the given problem that involves addition of similar fraction. (5 POINTS each)

1. Annabel and Gil were attended a debut party. Annabel eats 3/4 of the whole pakwan,

and Gil eats twice as much Annabel has eaten. How many parts of the pakwan they

have eaten in all?

2. Alex and Allexa were given P 200 by their grandma for their weekly allowance. Alex

received 3/4 amount of the money as much as Allexa received. What is the total amount

of the allowance did each receive in all?

V. Homework/Assignment

Look for a problem that involves addition in similar fraction and report it in front of the

class.
