At Planet Infinity, Kulachi Hansraj Model School, we celebrated 127th birth anniversary of famous Indian Mathematician Srinivasa Ramanujan. We did an interesting activity. Students were divided into two teams. One by one they were to speak a sentence in which a number had been used. Students of class 10C continuously conversed for about 6 minutes. Students of class 9D also did the same activity. For students of class 9G we changed the format of activity. Two groups were made and each was given 1 minute to say as many sentences as they can involving numbers. They all performed very well. I have recorded their videos as well.
