I gave my iPad to my grandchild.
How can I delete my iPad from my account?

You can take a look, if that iPad is under your name, remove it from your account.
See this Apple article : Check your Apple ID device list to see where you're signed in

Then your grandchild has to sign in with his own Apple ID on the iPad.
