I've worked in schools that have a cafe type system where children can independently choose to have a snack between certain times if they want and in schools where they stop their learning/play, tidy up and then sit in a circle and eat fruit etc together.
What do you do in your setting and why? And how do you work it? And do you like it?
I prefer the sitting in a circle and eating together because it's a lovely social time and a chance to talk and share with the children what they have been learning. But maybe I am in the minority?
