Try to make it to the other side without being tagged if you have the secret eraser.
Break students into two teams, each team gets one eraser. One team starts at one side of the playing area, while the other team start in the middle. Each round starts with a huddle, during the huddle the running team (team against wall/side of playing area) decides who is going to hold the eraser. On go, the team tries to run to the other side avoiding getting tagged by the students starting in the middle. If they get tagged, they sit down. If the teammate with the eraser manages to get to the other side of the playing area they score a touchdown for their team! Switch roles after each round.
Keep your heads up
