iPad for a kid-older/very used ok (Anywhere is Humboldt)

Looking for an iPad so that a young kid can install some apps to work on a few skills that their teacher wants them to focus on over the summer. Our current older, kid iPad is now so old that it won’t accept updates or download the educational apps the teacher gave us a free code for… anyone got any size or age of iPads that we could try? I think the iOS update we need it to be able to do is 10. 🙏 a little cracked screen or something would be no prob!
