DIVIDES DECIMALS /MIXED DECIMALS UP TO 2 DECIMAL PLACES (M6NS-Ig-116.4) day 3-4 CAREN D. LABASANO
2
DRILL: Number Tree: Pick a fruit pasted on a picture of a tree.
These fruits have number sentences You need to answers it.
3
48 ÷ 2.4 4.8 ÷ 2.2 3.6 ÷ 3 24 ÷ 0. 8 86 ÷ 2.2
4
REVIEW: What are the steps in dividing whole numbers by decimals and vice versa.
5
Why is it important to save?
MOTIVATION: Do you have things that you really need to buy? What do you do to buy these things? Why is it important to save?
6
If he earns ₱55.75 per week, how many weeks will he need to save?
PRESENTATION: Mario saves his allowance to buy a pair of rubber shoes that costs ₱ If he earns ₱55.75 per week, how many weeks will he need to save?
7
Comprehension questions:
What is asked? What are given? b. What operation should you use to solve the problem? Why? c. Let the pupils write the number sentence on the board.

PERFORMING ACTIVITIES
•Relay race to solve decimal division problems. Groups of four pupils. Each pupil will get a different task: divide, multiply, bring down, or subtract. • •When the teacher says "go," the person dividing will complete the first step of the problem and then hand the marker to the next person, who will complete her task. This will continue until the problem is solved. They are allowed to help their teammates, but they cannot leave the line or yell or another group may hear them! In order to win, they must not only finish first, but also have the correct answer. Possible problems: 77.21/3; 90.4/2; 5.15/5.
9
PROCESSING THE ACTIVITY
How did you find the activity? How were you able to find the answer? : To divide a decimal number to another decimal number: Change the divisor to a whole number. Multiply both the divisor and dividend by a power of 10. Divide as with whole numbers.
10
To divide a whole number by a decimal, change the divisor to a whole number by moving the decimal point. To move the decimal point in the dividend the same number of places, you will need to add one or more zeros. Then divide.
11
REINFORCING: Give the quotient. a. 36.2÷2.5=N b. 36.3÷3.6=N
c. 8.4÷ .2=N d. 25.5÷1.5=N e. 2.4÷1.2= N
12
SUMMARIZING THE LESSON:
How do we divide decimals mixed decimals up to 2 decimal places ?
13
Change the divisor to a whole number.
Multiply both the divisor and dividend by a power of 10. Divide as with whole numbers.
14
APPLYING TO NEW AND OTHER SITUATION
Divide the following mixed decimals by decimal. 1) 3.72 ÷ .06 = 2.) 4.84 ÷ .21 = 3.) 8.82 ÷ .42 = 4.) 1.21 ÷ .15 = 5.) ÷ .73 =
15
ASSESSMENT Divide the following decimals by another decimals. Choose the letter of the correct answer. 1..24 ÷ .04 = a. 6 b. .6 c d. .006 2.) .88÷ .02 = a b c d. 44
16
3.) .168 ÷ .08 = a b c d. 21 4.) .255 ÷ .05= a b c d. 511 5.) .728 ÷ .08 = a b c d. 911
17
Find the quotient of the following decimals and solve for N.
ASSIGNMENT: Solve Find the quotient of the following decimals and solve for N. 1.) ÷ 0.24 = N 2.) ÷ 0.32 =N 3.) ÷ .25 =N 4) ÷ 3.8 = N 5.) ÷ 7.5 =N
