Maths that’s mental
Mostly, kids have a phobia of maths in their minds. When students heard about maths, automatically their morale goes down. They considered maths as an extremely tough subject that they can not do master in that subject. Maths avoidance leads to less competency, exposure, and maths practice, leaving students more anxious and mathematically unprepared to realize learning goals. Mental maths is a group of skills that allow people to do maths “in their mind” without using pencil and paper or a calculator. Mental maths use in day-to-day life. It can help kids understand maths concepts better and get to the answer faster. Doing mental maths requires strong memory skills. Maths facts and other number concepts have to be retrieved from long-term memory. Our brains also use a skill called working memory to keep track of the steps needed to solve a particular maths problem.
When kids struggle with mental maths, it doesn’t mean they’re not smart. Kids develop maths skills at their own pace. Difficulty with mental maths could be a matter of needing more time and practice to “catch up.” Regularly practicing mental maths can improve other maths skills. Mental maths is useful in other ways too. It keeps maths facts from getting rusty. It can also help get to the answer faster.
For example, what is 27 + 85? It’s easier to do this in your head if you break the numbers down into their digits’ values: 20 + 80 = 100 and 7 + 5 = 12. Add those two totals and you get the answer of 112.
In olden times, people used to learn half, quarter and one and a half tables of maths. So, they never used a calculator for calculating bigger number calculations. Illiterate people also doing their transactions from their mind in everyday life. For example, a farmer who had 5 bigha land, produces 20 mounds of cotton and the 1 mound price is 900 rupees. Now, he wants to sell in the market so, he can easily do the calculation of the transaction without any help. Like, 9 X 2 = 18 and then multiply with 1000 so he will get 18000 as the total price of their cotton.
We are doing its kind of puzzles in our online class also because Gajera Trust believes in development, not only books. If you solve more mental maths, you can boost your IQ level and observation power. Students' confidence also increases by solving mental maths.
In this case, it helps to build a relationship between different things of numbers. One becomes aware of how numbers interact with each other, which is an important skill required to love maths. Maths concepts are built on each other and getting a sense of numbers is important to understand complex concepts. Mental maths relies heavily on memory. So if you have to find out 11% of 200; you will first do 10% of 200 = 20; then 1 % of 200 = 2 and then add the two. So 11% of 200 is 22. It may look challenging in the beginning but eventually, you get a hang of it. The applications of mental maths in daily life are myriad. It goes without saying you will look cool in front of your friends if you can calculate 37% of 650 without using a calculator. It builds your self-confidence and esteem. It improves concentration power and helps children to reduce mistakes while solving problems. It increases the accuracy of the calculation. This can result in a young student trying to calculate 610-130, and getting 780! However, by using mental math, a student will often use approximation so they will know what their mental calculation should be close to, and can adjust their calculations, resulting in a higher percentage of correct answers! The applications for this are countless, ranging from raising grades to helping activities that come up in everyday adult life!
