how to play dice champs

today totara class was learning about how to play dice champs 

first the entire class made a big circle and we were learning how to play with a big yellow  foam dice 

and so we started off with rolling the dice to the person you were versing and then we could say addition to the number
or times the number by 10 depends on what you want to choose and the first person to say it wins that battle but if you don't win the other person rolls the dice.
