The first step towards learning letter writing is by tracing. Kids are encouraged to learn and write letters by themselves. First, a child starts writing letters in a big box and is motivated to write in a smaller box. They can use either pencil or crayons on paper for writing. Writing in bigger boxes helps the child to improve their pencil grip as well as memorize the letter pattern. Learning to write with a big size followed by a small size is the best way to teach kids writing skills. Follow the instructions and have kids learn the correct formation of writing the letter S.
