Bored 3 year old...help!

So my daughter has a speech delay and has been home since mid March from preschool due to covid. She has a really short attention span and loves to be active. We have a big backyard. However. Her toys are getting old and boring. I see her walking around aimlessly from toy to toy and half enthusiastically playing. I used to set up painting activities and stuff for her but she would spend 5 minutes doing it then lose interest so it became more of a hassle than it was worth. She won't sit still to color more than a few minutes. He mainly likes her swing outside and to watch super simple songs and blippi. I have officially burnt out trying to entertain her and she seems burt out from the same shit every day. We live in California in a hot spot and can't do much. What are some things I can do? We have done:

Blanket forts

Kinetic sand

Play dough(even made some)

Painting

Wading pool

Sprinkler play

Chalk(shes not a fan)

Stickers

Daily walk

Coloring books

DiY car ramps

DiY indoor slide

She has a bike and scooter but hasn't learned to use either yet.

Please drop more ideas!!
