Chess is a good game to increase children’s concentration and it is also a good brain game that will help them to become critical thinkers. From the look of things, it looks like a complex game that children cannot grasp. In reality, chess can be learnt by anyone who is interested. If you want to teach children how to play chess, the tips that will work best are:

• Be Patient: Remember that children do not have a fully developed brain, and they may not understand things as easy as adults do. Be patient with them. Do not get irritated when they make mistakes. You may need to explain the rules of the chessboard over and over, but that should not discourage you.
• Focus on Fun: Do not make the game of chess to be a competitive thing. It is about having fun. Even as you teach them, you should not forget to have fun. Name the queen, use the opportunity to teach them about the origin of chess, and other interesting details that will get them to be engrossed in the game.
• Schedule Time: Children tend to learn better when there is some sort of routine to help with learning and for them to appreciate it as part of their structured activity. When they are anticipating that they will have time for chess, they will not feel frustrated or bored when they have to start playing. The scheduled time should be convenient for both the trainer and the child. Do not yank them from when they are playing with their friends.
• Be progressive: Avoid the mistake of lumping everything together and expecting the child to understand. Take things progressively and be willing to pause when you realise that the child is struggling to understand. Encourage them to ask questions and use different teaching tools like using mobile games.
