I'm all about teaching students to play independently and to play with other children without adult support (or with minimal adult support) in the classroom.
Play is such a great functional skill! Not only is play an important social skill... but think about it this way too:
At home: If children can play independently or with siblings without adult support- it can give families
the opportunity to cook, do chores, or practice a little self-care without needing to constantly tend to the children.
In the classroom: If children can play independently or with peers without adult support- it can give teachers the opportunity to work in small groups or 1:1 with other students!
