New activities for 9 week puppy on crate rest

I have a mini Aussie who has now been on crate rest with a fractured leg for 3 days… and we’re both already going insane. I need advice for new activities to keep her stimulated and tire her out! All she wants to do is run around. She is on gabapentin 3 times a day already, and I’d rather not add trazodone

I know there are tons of posts out there on crate rest, but my particular problem is that this happened on her second day home, so the only command she (loosely) knows is sit and she could not care less about treats/food/chews so teaching her new ones is hard. Potty training has been difficult too, as I don’t want to take her out of her crate at every cry, but I also fear she may need to go.

She likes her puzzle mat, and will play tug for a bit, but I need some more activities to rotate to tire her mentally and I’m totally stuck.

I want her to heal well, but she is so sad and I just want her to know she’s not doing anything wrong:(
