For this you should have a proper planned tracing schedule of daily one tracing paper with jumbo crayons. You can download our free tracing worksheets and put them in sheet protectors to reuse them many times. All that you will need is a thin kid suitable marker/sketch and a folder to organize these tracing sheets. Believe me there nothing more important than pencil control that kids learn while tracing different lines. Staying on dots and moving from one dot to other to form i line or a picture will definitely teach them to write in lines in their schoolbooks.
