At school, or home??
At school:
1) as kind of a fund raiser, we threw pies at our teachers for 1$
2) My class is so into animals xD we made 4 teams, and everytime a team mate got an A, that team would get a point, the team with the most points at the end of the month gets a treat from the other teams
3) we convinced our teacher for a record brakeing club. One we tried was "The most cups stacked (stackers) in a single pyramid"
4) We had a HUGEE hide and seek game outside one day
At Home:
1) Me and some friends split up and walked around for about an hour, collected random things that we found and tried to make somthing big out of them xD
2) Does it snow there? If so, You could make plans for a snow fort (if there is that much snow)
That's all I got! sweatdrop
