 Ask the whole class to stand up.
 Split the whole class into groups.
 Tell each one of you is ‘A MONTH’
 Say: please come one year from the left side, and, sit down. [see whether the group coordinates and make a group of 12 students]
Repeat: 1 year = 12 months
 Say: two years from the right side, and, sit down. [see whether the group coordinates and make a group of 24 students]
 Ask them all to stand once again and repeat the activity with 3 years [36 students], four years [48 students] etc.
 Conclude the discussion on 1 year = 12 month.

 Discuss with the whole class about how we figured out number of students to present years or months, etc.
