Do you know playing chess increases your creativity, awareness, and problem-solving skills?
The earlier a person starts playing chess in his/her life, higher the brain functions. So, It is recommended to teach children to play chess at the earliest.
We need not enroll them in a professional chess coaching class and make them a grandmaster, just teaching them how to play and encourage them to play regularly will make wonders. But If you want to, feel free to do it.
