To understand your question better, could you please clarify what you mean by a "spelling disk"?
Here are some possibilities:
* Are you talking about a physical object? If so, can you describe it? Is it a circular piece of plastic or metal with letters on it?
* Are you referring to a digital tool? Is it an app or a website that helps with spelling?
* Could you be thinking of a spelling bee? This is a competition where participants are asked to spell words.
Once you clarify your question, I can provide you with a more helpful answer!
