Hello there, @TannerDunn ...
I would suggest that you reach out to the Wake County Public School System's Canvas administrator to help you get rid of that Newbery Book Club item. I don't think you'd be able to get rid of that on your own. However, your school's Canvas administrator should be able to tell you if this can/cannot be removed from your Canvas account. I found this page on their website which may be of help to you:
Guides to Technology / Homepage (wcpss.net)
Good luck as you have these conversations at WCPSS! Let Community members know if we can do anything else to help you. Take care...
