Slide2Slide3Each PAIR OF PARTNERS will begin with $500You will see each problem for 10 seconds before deciding how much of your money you want to RISK…you will place your bet and share it with your neighboring partners that you are competing against.Each problem will be displayed for 1-2 minutes. The PARTNERS must then work together to determine the solution.You may only bet UP TO HALF of your money at any timeYou may choose to bet $0 ONE TIME ONLY
Your best must be in increments of $50, so round down if you are shortYou are responsible for keeping track of your $$ (be honest…) If it’s correct, partners add the amount they bet to their total. If it’s incorrect, it’s deducted from their total.The group with the most $$$ at the end wins.WE WILL ALSO LOOK FOR THE RICHEST PAIR OF PARTNERS IN THE OVERALL CLASS. HAPPY BETTING!!
