This is a great fitness activity can last as long as you want it to. I split the students into groups of 3 or 4. You also will have to get some play money at the dollar store. I laminated it and then put numbers 1 -6 on the back of the bills. I put them all in a box. I stand in the middle of the gym one student from a group comes and draws out a bill. Their group runs to that sign and they must do the activity that corresponds with the number on the back of the bill to earn that money. At the end they count up their money to see what group earned the most money. The students work hard and love this activity.
