One person is “it” and closes their eyes. The rest of the class goes to one of the 4 corners (or 4 designated spots) of the room.
“It” calls a number and children in that corner sit down. If they don’t sit down, they are ‘out’. Continue until there are 6 or 8 left, then you tell them there must be only 2 in each corner or, when 4 left, – one in each corner. The last person left – gets to be “it”.
