Green was the silence, wet was the light, the month of June trembled like a butterfly. Summer vacation is a great chance that can cheer up our souls and refresh our minds. It’s a time that we all keep on waiting the whole year impatiently. After several working days, we all need a break. And summer vacation is the best break of the year. As parents are the first and the most important teacher for a child, we can encourage our child to participate in many educational activities at home and promote his/her quest to learn. Working together will not only help your child to build, learn and develop his/her skills but also strengthen your bond with him/her.

Father’s Day is celebrated every year on the third Sunday of June in most parts of the world. This year Father’s Day will be observed on 19 June 2022. The day is observed annually to recognise the contribution of fathers and their importance in the lives of their children. International Father’s Day is all about honouring the joys of fatherhood and the bond shared. In the light of above occasion, we would appreciate if the students send some pictures or videos \"SPENDING QUALITY TIME WITH YOUR FATHERS.\" YOGA AND MEDITATION Practicing yoga can provide kids with physical benefits such as strength and flexibility, but also improved emotional control and a boost of self-confidence. We would also love to see if the students of our school spare 10-15minutes of their day doing some Yogasanas at home. Also share some pictures of the same with their class incharges.
