My English class had recently participated in the Global School Play Day, and here is a website if you want to know more about it in detail. I learned that spending time with friends playing games can be a lot of fun. I enjoyed playing Milles Bornes, which is a French Canadian Driving game for those who can not drive; I was not doing so well in the beginning, but caught back up.
The only teachers at my school that decided on doing this were English teachers, it would be cool if every teacher did this for the whole day. It could also be cool if this became a national school day of unstructured fun.
