My son lacking in concentration?

You 1st ask your son is their anything in his mind which is irritating him alot you try to find out 1st if its not their anything then ,You ask your son to do some meditations or u try one method just marked one point with pencil on the wall ask him to stair that point for 2 to 5 mins it is a type of meditation..with this it improves a confidence level and helps to concentrate also which has help me alot and it worked for me..!!

And if its their anything going on in his mind then try to solve his problem then ask him to do meditation he will feel relaxed and will able to concentrate on studies..:)

at the age of 10 to 15 years boys do show these changes. just talk to him and try to motivate him for studies. he may have his personal like and dislike for subjects. at hope try to make subjects more interesting. check weather he is auditory, visual and kanast.. learner.
