LESSON 1

​Do you love bread?

​(Guilty about that. I REALLY love bread! :p )

​On a certain bakery, there were 230 monay breads to be placed on trays. The baker wants to arrange them in either 2, 5 or 10 rows. Would it be possible for him to arrange the breads?

LET US ANALYZE THE PROBLEM FIRST

by answering the following:

Multiple Choice

^Problem:​

^{On a certain bakery, there were 230 monay breads to be placed on trays. The baker wants to arrange them in either 2, 5 or 10 rows. Would it be possible for him to arrange the breads?}

Question: WHAT DID THE PROBLEM ASK YOU TO FIND?

• The total number of monay breads.

• If it is possible to arrange the monay breads in either 2, 5 or 10 rows

• If the baker wants to arrange the monay breads

• The one who ate the monay breads

WOAH!!! THAT WAS QUICK!!!

READY?!?

BEGIN!!!

Multiple Choice

^Problem:

^{​Jaira collected 70 stamps. Can she share that equally to 2 friends? 5 friends? 10 friends?}

Question: WHAT DID THE PROBLEM ASK YOU TO FIND?

• The total number of stamps

• The total number of friends

• If the stamps can be shared equally to 2, 5 or 10

• If Jaira has stamps to share

Now, take a look at this one.

(next page, please... )

​How do we find the factors of a number using divisibility rules?

We recall and apply the rules on divisibility for 2, 5 and 10.

Divisibility rule for 2

- All even nos. are divisible by 2

- Numbers ending in 0, 2, 4, 6, 8​

​

Examples:

 32, 144, 186, 328, 510 . . .

Divisibility rule for 5

- Numbers ending in 0 and 5 are divisible by 5

​

Examples:

 85, 120, 265, 300, 520 . . .

Divisibility rule for 10

- Numbers ending in 0 are divisible by 10

​

Examples:

 60, 130, 270, 400, 670 . . .

Time for SOME brain exercise!!!

YOU WERE AWESOME THERE !!!

NICE ONE!

One more lesson, then we're done.

Let's BEGIN!

​Uses divisibility rules for

3, 6, and 9 to find common factors

​M5NS-Ib-58.2

LESSON 2

Are you a member of the student council?

As a member what do you usually do to help your co-students in school?

​Now, let us analyze the problem that will follow.

​The school janitors are setting up the hall for the students’ council meeting. There are a total of 297 monobloc chairs which they have to set up in either rows of 3,6 or 9. Which are possible set ups?

If you were one of those who have to set up the hall, what would you do? Would you got ahead and try to make rows of 3, 6 or 9? Is there an easier way?

​Let us group the total number of  monobloc chairs which is 297 into groups of:

​297 ÷ 3 =

​297 ÷ 3 =

​997

​297 ÷ 3 =

​997

POSSIBLE

​297 ÷ 6 =

​297 ÷ 6 =

​49.5

​297 ÷ 6 =

​49.5

NOT POSSIBLE

​297 ÷ 9 =

​297 ÷ 9 =

​33

​297 ÷ 9 =

​33

POSSIBLE

​297 monobloc chairs can be set up in 3s and 9s.

​Let us have another example.

Nena’s garden has 414 bougainvillea plants. She wants to arrange them in either rows of 3, 6 or 9. Which are the possible arrangements of the plants?

​414 ÷ 3 =

​414 ÷ 3 =

​138

​414 ÷ 3 =

​138

POSSIBLE

​414 ÷ 6 =

​414 ÷ 6 =

​69

​414 ÷ 6 =

​69

POSSIBLE

​414 ÷ 9 =

​414 ÷ 9 =

​46

​414 ÷ 9 =

​46

POSSIBLE
