The curricula calls for "the child will learn to write his name". I don't think that is unreasonable.I would feel responsible if she got to second grade and the teacher took the papers and looked at "Pod" and wondered "wth?" She'd have to ask what "Pod" was and then she would ask her to write her given name only to find out she couldn't. My way, The child can write either her given name and if the teacher allows, "Pod."Why not just teach him to write the name he goes by?
Seriously. Indians often go by nicknames...if your student is named "Gina" but goes by "Pod" and that's the name her folks call her, who are you to refuse to teach her to spell that name?
