dice champs

in Totara class  we played dice champs. The way you play dice champs is you get into groups of  two or three .You get a dice it can be a 12 sided dice or  any dice will do.  Then you are ready to play. Then get your partner. And  get a dice. And if you roll a 4 or more. You have to double that number like this. If i got a 5 i will have to double that number. who ever gets the correct number they get to roll the dice. who ever get it first they get to roll if it is a Thai roll again. If you are not sure count like this i got a five right. so i will have to count 5 more and that will be 10.do you get that. the game is supposed to teach you how to add up.
