Splitting

Quick calculations can be performed more easily if the numbers are split into more “manageable parts”. The best part of Splitting is that it helps us do the calculations mentally and can be applied to Addition, Subtraction, Multiplication and Division.

What is important in Splitting is to find the correct place to split so as to avoid carry.

Splitting can be used for any operation, viz. Addition, Subtraction, Multiplication, and Division.

I will explain you all with the help of examples for each of above cases.

Smart way to remember Table upto 9

Remembering tables has always been tough for kids.

They have to start from 1 x 1 to 1 x 10, then 2 x 1 to 2 x 10, ….., 10 x 1 to 10 x 10.

We ask them to remember 100 multiplications. However, we don’t need to remember all these multiplications. There is an easier way to remember these tables.

1st point: Any number multiplied by 1 is  the number itself.

               For example:            1 x 1 = 1;          4 x 1 = 4

2nd point: Any number multiplied by 10 is that number followed by 0.

               For example:            2 x 10 = 20;      9 x 10 = 90

3rd point: This is the unique part. You just need to remember the below table. It has only 36 multiplications

If you know 2 x 3 = 6, then effectively you know 3 x 2 = 6, and so on…

Kids would love to remember 36 multiplications rather than 100 multiplications.

When I taught this to my kids, they just loved it!
