You could get her to plan some projects. E.g.
Use Pinterest or old fashioned magazines, scissors and glue to create mood boards for redecorating her room.
She could do the same with a personal makeover - have fun exploring new hairstyles and clothes ideas.
Get her to design her dream home.
Sort out clutter and clean some things to give to charity.
Keep a diary.
Do an online fitness course.
Follow some podcasts.
Read a book or two. Download onto kindle or use Audible if you don't want deliveries at the moment.
If you have a garden, get her out there to do some garden maintenance with you, or to take some nature photos, or set up some bug hotels, hedgehog shelters etc if she is still young enough to be interested in this sort of thing.
Get her to set herself a challenge - to learn an instrument or do a fitness challenge (eg press ups, pullups, burpees etc) that increases each day.
Go outside every day for walks in nature, bike rides etc
Watch some classic movies with her
Ask her to help with some DIY
Help her pick up some key life skills - now is the time to learn how to do her own laundry, make her own bed, polish shoes, change a lightbulb etc if she doesn't know already
