3 yr old in home Preschool ideas

[petesgirl]

I had signed DS2 (3 yrs old) up for Preschool 2 days a week starting this fall. I haven't heard anything from his teacher yet but she is a retired school teacher and the Preschool crowd is probably the hardest to enforce masks and distancing with so I'm fairly certain she won't be teaching. I'd like to find a short curriculum we can do for 10-15 mins a day....any recs? I keep seeing Preschool Prep advertised, anyone try it?
Also, what I can do about learning social skills? That was my main reason for wanting him in Preschool anyway, not so much the academics. He really needs interaction with other kids and time away from mom. Not sure that's really even possible in this situation.
