How to improve a child's handwriting
Show her how to work within the lines.
Lines can help her get her proportion correct, which in turn makes her handwriting more readable. If she's having trouble with it, show her the best way to do it.
Use primary handwriting sheets that have colored lines as guides for each letter. Capital letters should go from the top line to the bottom line, and they should be twice the size of a lowercase letter.
