wow! she sound amazing.
How about some science experiments, art type projects or legos. We have a kit about bubble science for the summer. Panama waterways (Brio) is great fun and kids can learn about pumps and currents.
This is not my expertise but try to relax and enjoy the ride. I would follow her interest leads. Go up levels in games/toys as she is ready. If she takes an interest in something go get books about it. How about some things to be challenged and some stuff that is just fun? I think it nice to enjoy things that are simple too. It feels good to make a colorful paper chain that have stickers, stampers or marker decorations to hang on the stair rail. String some popcorn and dried fruit for the birds.
Hope this helps. Mostly just have fun and enjoy this time. Take lots of video and pictures.
A book called Montessori play and learn has some good ideas.
