Greater than and less than
Split into teams of three.
Everybody picks up a ramdom ball each.
The team place themselves from left to right to form the highest possible number.
Which number are you?
Shoulder to shoulder the teams makes laps around the room while holding the balls in front of them.
Half the teams walks clockwise and the other half counterclockwise.
When one team meets a team that has a higher number than them, the team must make themselves as small as possible. The team with the highest number must make themseves as tall as possible. Walk forward like this until you meet a new team.
Variation: Try teams of four to practice figures higher than 1000.
