I am an ICT Teacher and ISA Coordinator at International School of Scholars, Nagpur, Maharashtra(INDIA). I have nearly 25 students of age group 10 to 15 who would like to interact with students in UK through emails sharing how do they celebrate Important Days of International Importance in their Schools, which all International days do really carry a lot meaning to them, their school and their country.
