HOLIDAYS HOMEWORK
ASSIGNMENT
CLASS XII
SESSION 2017-18
New session, new books and new friends have kept the kids
buzzing for a while and now the much awaited vacation is
here! Summer Break is the best time of the year for parents and
children alike. While parents get to spend the maximum time
with their young ones during this period; for kids, it’s time for
family bonding, loads of ice cream, time to visit grandparents
and getting pampered to no end.
Summer vacation can also be a time for learning with lots of
activities around. Parents may try out something different by
arranging a visit to an old age home or an orphanage and
motivating the students to spend some time with the people
there. Imparting love and affection amongst others not only
gives one happiness but also instills a sense of social
responsibility that every individual must imbibe to contribute
towards a better world. Learning Yoga, Meditation/ De
stressing techniques also can help to prepare you for the
academic challenges ahead. The focus should be on a learning
which is aimed at evolution of a child into a holistic individual.
Keeping this in mind, the subject-wise assignments given as
holiday homework have been planned with the view to make the
optimum use of the youngsters’ energy and give a vent to their
creativity so that the process of learning continues during the
vacations as well. Parents’ support and encouragement is
sought to ascertain that the budding minds take out some time
from long summer days and switch on the search engines of
their minds in exploring and learning.
We hope that the students enjoy these holidays thoroughly in a
way that they inculcate some values, virtues and knowledge in
the bargain!!!
