Mental Math - helps your child to get that extra edge!

Jan 13, 2020 | Mississauga

There’s an app for everything. Including a calculator app. What’s the need then for children to learn to do calculations in their head?

Studies have shown the mental math has several benefits:

​​Helps stimulate the brain and increases confidence in working with numbers - Kids who feel confident perform better in tests. Additionally, kids who do well in Math, tend to do well in school overall.

 

Helps make learning math fun - Kids enjoy doing mental math and math makes classes interesting. They are excited that they can calculate things in a shorter time compared to taking out a calculator and typing in the numbers. 

 

Helps in making knowledgeable decisions in everyday life as an adult - Mental math will be very useful in calculating things like - price after tax, discount amount, change for cash required.

 

Here are a few fun tricks:

Addition of big numbers 

Round them up to the nearest ten, and then add those. 

Example: 346 + 438 = 350 + 440 = 790

Then subtract the last digit from 10 and add those up

10-6 + 10-8 = 6

Subtract this above answer from the original addition.

790-6 = 784

So, 784 = 346 + 438

 

Check Divisibility of Numbers

By 3 - The last two digits are added together and that is divisible by 3

By 4 - The last two digits are 00 or divisible by 4 

By 5 - The last digit is 5 or 0

By 6 - Even number and the test for 3

By 8 - The last three digits are 000 or divisible by 8

By 9 - The last two digits are added together and that is divisible by 9

 

Multiply in parts.

This is an important foundation for advanced algebra.

For example: 4 × 83 

Multiply 4 × 80 and 4 × 3

Add the results 320 + 12 = 332

Therefore, 4 x 83 = 332
