“Play is often talked about as if it were a relief from serious learning. But for children play is serious learning. Play is really the work of childhood.”
Playing for too long has been downplayed, looked down, labelled as “not serious” but I think kids learn best that way. What they learn with pleasure will be very hard to forget. Personally I still remember course contents from relax and fun teachers; they were hardworking yes, but fun and easy going too. The so called “serious” / “grumpy” ones, my classmates and I would usually forget their course contents once their final was over.
When it’s fun kids like it and ask for more. So many kids hate school and this needs to change (I was and still am one of those, unless when a specific class was fun and enjoyable).
On a kindergaten level, I think a four year old should be playing. Many end up lacking social and life skills because they were never allowed to play.
