1. Quiz: Ram takes bath once in two days. Shyam takes bath once in three days. How many times in a month do they take bath on the same day ?
2. Stand on the ends of the classroom making a huge circle. Start counting from 1. When it is time to say 4, say Meow. Again at 8 say Meow. If you say the number (table of 4) you are out. Let us see who wins. Repeat this game for table of 6, 7, 8 etc.
