How to improve writing habits in kids

We need to make them practice. I am also facing same problem. My son don't like to write or draw but he can do.

 

Make him write on a dotted lines within the four lines. Like Padmash said, practice, practice, and more practice.

One more thing, don't expect them to write PERFECTLY....like letter "X", my son used to write one line straight and another line extremely slanted.

Make him do more fine-motor activities like paper crumpling and grains sorting.

 

It is really difficult to transition from slate boards to books...he has to develop the wrist control needed to keep his writing within the lines. All you can do is give him lots of practice and he will develop the skill only when his muscles are ready for it.

Tape paper on the wall and let him draw/ paint/write on the vertical surface. That helps in wrist isolation. You can also tape the paper under a chair or a low table...he can lie down under the piece of furniture and draw/write. Make it a fun and goofy activity to help him buy into it. This too will help in wrist isolation.

He can also help knead chapathi dough...think wrist movement all along.

While you work on the wrist control you can also make him conscious about the writing process...use descriptive language like to narrate the steps to forming letters...'start at the top, bring it down, bump the line, curved letter, straight line...'

 

You're welcome Malathi.
Here's a good website with info on different aspects of fine motor development. It is for the classroom and some of the activities use materials available in the US. you can get a better understanding of the range of skills necessary to developing good hand function and substitute local materials as and when needed.
