2. Make a team of 2 students. Write chits with numbers from 0 to 5. In a team, each student picks one chit and gets a number. Support team 1 got the numbers 2 and 4. The first student has to find value of 24 and the other student has to find value of 42. Whoever gets the higher value wins the game. Repeat the steps for 5-6 times. Add up the answers to find who is the winner in the team. | 2. Make a team of 2 students. Write chits with numbers from 0 to 5. In a team, each student picks one chit and gets a number.
