The students love this warm-up. Put cones around the perimeter of the gym. I use 8 with 8 different color crayons, one under each cone. You must color a master sheet. Then put the students into teams of 4 or 5. They all must keep one hand on a hula hoop the whole time as they run from cone to cone to find the specific color they are looking for. You whisper to one student on each team the letter they are starting with and what color it is. When they find the correct color they run to you to find out the color of the next letter. This is a race, and you should start all the teams with a different letter and they must wait for the go signal. Look out they may run you over on this one !
