Dear Parents,

‘Exciting time is here again! It’s time for Summer Vacation and fun filled activities.’ Children are

power houses of potential which needs to be tapped and channelized in diverse ways. They should be

encouraged to develop intellectually and physically. Summer Vacation is the best and fruitful time for

learning and for nurturing creativity. The Holiday Homework designed would not only enhance

achievements of your child but would also teach your child to work independently and would improve

his/ her basic academic skills, such as reading, writing, and spellings. Here are a few suggestions that

you may keep in mind-

Let the child do his/her homework. Parents can act as guides & facilitators.

The homework should be done as per the instructions given. It should be neatly labelled and

the name, class, section of the child should be mentioned clearly.

The last date of submission of holiday homework is 18th July. No homework will be accepted

after the last date.

The holiday homework will be graded and is a part of CBSE assessment.
