Holiday Homework – (2017-18)
Class – IX
Dear parent,
“Exhilarating days are here again! It’s time for Summer Vacation and fun filled activities”
Children are reservoirs of latent aptitude which needs to be explored and channelized in diverse ways. We feel that it is
very important to fire their imagination and foster an outlook that helps them explore, discover and rediscover. Children
should be encouraged to develop intellectually and physically. Summer Vacation is the best and fruitful time for learning
and creativity. It is the time when you can connect with your child in many ways.
The holiday homework is so designed that it would not only enhance achievements of your wards but also help to
augment interaction.
Remember that Summer Vacation is the time to relax and enjoy. So spend these holidays creating a nurturing and
stimulating environment filled with fun, frolic, learning and education.
