MULTIPLYING NUMBERS USING LINES

Here is a fun way to teach pupils and students how to multiply numbers using lines. You may represent each number by parallel lines then find their intersections. Some say that this is one of the methods used in Vedic Mathematics, a system of mathematics consisting of 16 sutras or aphorism.

Example 1:

STEP 1: Represent the first number by parallel lines. Separate the number of lines per digit. Each digit should represented by a group of line(s).

















STEP 2. Represent the second number by parallel lines but in opposite direction as the first set of lines. The red lines represent the first number and the blue lines represent the second number. Take note of the intersections of the lines.
















STEP 3: Group the intersections that are aligned vertically and count the number of intersections per group.

STEP 4: The number of intersections in each group represents the digits of the product.

Therefore,

What if the second group of numbers exceed 10? Let us have another example to illustrate this scenario.

Example 2:

Follow the same process as above. Steps 1 and 2.

Step 3:

 

Step 4:

Therefore

Now it's your turn to try this method of multiplying numbers. Try to answer the following in a clean sheet of paper:

1) 34 x 24

2) 35 x 51

3) 43 x 52

4) 36 x 63

5) 72 x 42

You can share this to your your younger brother or sister, to your cousins, to your friends, classmates...

THE VALUE OF MONEY

This is written by an anonymous writer. It talks about the value of money and its limitations. I would like to relay this to those who were overpowered by money, setting themselves up high in a pedestal, and forget to look back to where they came from and to whom they were with - grasping greed, power, and self-centeredness. 




Money can buy a bed, but not sleep;




Money can buy books, but not brains;




Money can buy food, but not appetite;




Money can buy finery, but not beauty;




Money can buy a house, but not a home;




Money can buy medicine, but not health;





Monet can buy luxuries, but not culture;





Money can buy companions, but not friends;




Money can buy flattery, but not respect.


In mathematics, money is integrated on topics that deals with practical problems. Money math develops students' everyday math skills. It involves topics such as simple interest, compound interest,  annuities, amortizations, sinking funds, and the like. It creates a link between mathematics and our everyday life. 


Money is a part of our practical life but it does not mean that we let it overpower us. Control it and live a happy life!
