At our school they go out in anything pretty much. Two downed trees recently means in properly high winds they don’t go out. Snow just means they have to choose, on the field and you are fair game for a snowball fight against anyone else there, including staff, or the yard for snowball immunity. No swapping though!
This week though from Tuesday on there. Has been no snow, just rough ot rounded lumps of ice as far as the eye can see. No fun for anything (although it was a good test got my ice tyres) so they have been kept in.
No fun for any of us but they simply couldn’t play out, so yes, they go stir crazy. We could just close the school instead if you would prefer… 😉
