YOUR ANALYSIS
Why is there a need to make a survey of available materials before making your own materials?
1. To collect information from a part of a group or community, without trying to choose them for overall representation of the larger population. I need to conduct several of these before I get a sense of how the I I can make my own materials.
2..This will give me the most accurate information and these will be my basis on making my own materials.
3. If the materials that I observe are effective I can apply it in making my own materials if it is not effective I will create my own strategy in improving or I will change the instructional materials that I've seen in making my own materials.
YOUR REFLECTIONS
What materials did you like most?why?
Hand outs and Books because in using this materials the teacher can easily discuss her lessons.The students will not only imagine the words that the teacher discuss to them with the help of this materials they can gasp the information with reading the content of the book and handouts together with listening the teacher discussion and also the students can fully understand the the topic if they will asked questions and clarifications.
What difficulties did you encounter in making the materials?
Finding specific topic for the content of the materials, it takes time to encode the details of the topic, I need also to put brief details so that content of the topic will not consume too much pages.
How did you overcome it?
I make it sure that the materials that I made is already prepared a week before I will be using it.
Make suggestions to the teachers in the preparation of teaching materials.
In preparing the material like handouts it should be prepare earlier before it will be use in the discussion to avoid problems and the content of the hand out should be brief so that it can't consume to much money.

LEARNING ACTIVITY 5: PAPER WORKS ( HAND-OUTS USE)
Name of FS Student: Gregore,Ruviejen P.
Course: BSEd-Math3V

Grade Level Observe:
A HAND OUT
Subject matter: Adding,Subtracting, dividing and multiplying decimals
Content:
DECIMALS
Decimal means based on 10 ( from
latin decima means a tenth part) but a decimal number usully means there is a
decimal point.
14.295
1 is the tens
4 is units
. decimal point
2 is the 1/10( tenths)
9 is the 1/100 (Hundredths)
5 is the 1/1000( Thousandths)
Note: The digit to the left of
the decimal point is a whole number ,4 for example.
As we move further to the left,every digit place get 10 times bigger.. As we move further right, every digit place gets 10 times smaller.
All rational numbers can be written as
either terminating or repeating.
TERMINATING DECIMAL AS A FRACTION
a. 0.8 =8/10
Read
as 8- tenths
b.0.25=25/100
Read as 25 -hundreths
REPEATING DECIMAL AS FRACTION
a.Write 0.333... as a fraction
Solution
x = 3.333...
let x represent
the number.
10x = 3.333..
Multiply by 10
because 1 digits repeats.
-x = 0.333..
_____________
Subtract to eliminate repeating decimal.
9X = 3
X=1/3

ADDITION AND SUBTRACTION OF DECIMALS
ADDITION AND SUBTRACTION OF DECIMALS To add or subtract decimals: i.If it is necessary,write the numerals in co column so that the decimal points are directly under each other.Zeros may be annexed to the numerals naming decimal fractions so that the addends may have the same number of decimal. i.) 0.39 + 4.6 i. ) 8.4 - 2.76 0.39 8.40 + 4.6 - 2.76 ________ ___________ ii.) Add or subtract as in the addition of whole numbers. ii.) ii.) 0.39 8.40 + 4.6 - 2.76 ________ ___________ 4 99 5 64 iii.) Place the decimal point in the sum or difference directly under the decimal points in the addends or subtrahend and minuend. iii.) iii.) 0.39 8.40 + 4.6 - 2.76 ______ _________ 4.99 5.64 |
MULTIPLICATION OF DECIMALS
To multiply decimals: 1.Write the given numerals in column and multiply as in the multiplication of whole numbers.The decimal places point in the multiplier does not necessarily have to be unde the decimal point in he multiplicand. 2.Find the total number of decimal places in the factors and point off in the product, counting from,right to left, as many decimal places as there are in the factors. 0.8 --------- 2 decimal places
x 2.4 -----------1
decimal place
_______
332
166
_____
1.992 --------- 3
decimal place
3. When the product contains fewer figures/digits than the required number of deimal places,prefix as many zeros as are necessary. 0.25 --------------2 decimals places
x 0.03 --------------2 decimal
places
0.0075 ---------------4 decimal places
DIVISION OF DECIMALS
To divide decimals: 1.If the divisor is a whole number, a.divide as an division of whole numbers. b. place the decimal point in the quotient directly above the decimal point in the dividend. Ex 2.9 5 | 14.5 10 45 45 0 2.If the divisor is a decimal, a. make the divisor a whole number by multiplying it by a power of 10 or by simply moving the decimal point to the right of the last figure. b. move the decimal point to the right as many places as you moved the decimal point in the divisor. ____ _____ 0.4 | 9.2 --------------4| 92 c.divide as in the division of whole numbers and place the decimal point in the quotient directly above the new place of the decimal point in the dividend. 23_ 4 | 92 8__ 12 12 d. when the dividend contains fewer decimal places than required,annex as many zeros as are necessary to a decimal dividend. |
LEARNING ACTIVITIES:
SEATWORK
a. Express the following decimals as fractions in simplest form.
1. 0.7
2. 0.05
3.9.18
4.0.8333....
b.Perform the following operations.
1.0.56 + 6.449
2. 12 - 8.29
3. 19.2 x 23.06
4.8.75 ÷ 0.42
|
After the discussion I will give activities like seat works to know if they understand the topic and if the result of the quizzes are low I will give more examples so that the students will fully understand the it.
|
TOOLS
In the presentation,describe how the tool was used in a particular lesson/time.
The lesson is appropriate for 2 hours it will cope up the topic of decimal numbers it could not be done without visual aid.The discussion will begin in discussing on how to add,subtract,multiply and divide decimal numbers.

YOUR ANALYSIS
Which feature of the hand-out is not effective?
There are no feature of the handout that is not effective since every content are pacific for the topic.
What measured by assessment plan?Is it process or product?
It measure the student understanding therefore it is a product since I discuss the topic to them, give material and specific example with the assessment.
YOUR REFLECTION
Recall any difficulties encountered in making hand-outs?How did you overcome them?
]
It is difficult to find a topic and summarize all the data and to find specific learning materials.It is also difficult to make learning materials for the topic.It is also difficult to make learning materials if there is no learning resources.
I try to find a way to overcome that difficulties I plan the activities in an earlier time so that I can fixed unexpected problems in my presentation.
