The first step to start off with is to let the child spot the alphabet that he/she remembers. During childhood, the child enjoys making marks on the papers. Move your hand along with theirs to start writing alphabets and let them pronounce those alphabets with you as they write them. Provide them with a plenty amount of writing supplies, mainly pencils and colors. Get a white board with different color markers and make sure to keep it in a place at your kid’s eye level so that he will be promoted to write. Encourage them to write their own stories to express their imaginations as well as their expressions about their writing. Tell them to choose a picture of one person and try to write a narrative imagining that they are that person. They have to concentrate on details like job, hobbies, whether single or married, children, and facts that they think are interesting. (http://www.babybirdproductions.com/bbpadultcreativitytips.html)
To proceed further, get beautiful diaries and let them keep those diaries as well as journals to create interest in writing and tell them to spend at least 15 to 30 minutes daily and write about the interesting things that they did or are planning to do during the day for example, making new friends, going on a field trip etc. Try to get them involve in first asking about their favorite things that they would like to eat and then let them make a grocery list and note down their favorite things in the list of grocery items. Once you get them, let them write short thank you notes with creativity to express their joy and appreciate their talent that they have used in their work. To develop further interest, play games with them which would include communication through writing. Give preference to play acting and let them choose any character that they like the most and let them write that character’s part from the play. Make up a situation and let them find a solution of it through their writing ideas.
