My kid knocked my ONN tablet off the table and cracked the screen a little and now my touch screen wont work
Patricia Lightner that crack may have ruined your digitizer. Your Onn tablet is a bit off-brand so it may be harder to find a replacement touchscreen. Let us know what model it is so we can try and help you out further.
There is an adapter called USB OTG (Universal Serial Bus On The Go) that you can get online on walmart.com for a few dollars. Then, get a keyboard and mouse combo like this one: https://www.walmart.com/ip/Logitech-MK27… and as long as you don’t break the actual screen inside (like the way i did, help?) you should be good
