1. Count the number of students in your class. Count the number of students in your school. Count the number of children in your village. Count the number of stars in sky at night. How big can the numbers be? Is there any biggest number after which there can be no other number? Discuss and share

2. Play in pairs. One student ask the other to think of a number. Multiply the number by 2, then add 2, multiply 5, then add 5, multiply 10, then add 10. Ask the friend for answer. You can guess what the number is. Trick is ignore the units and ten's place digits. Consider the left digits, subtract 1 and that is the number thought by the student.
