SUMMER HOLIDAYS

HOME WORK TRAVELLING AN EXTRA MILE.......

2

Dear Children,

Holidays are always a welcome change. With summer

break round the corner each one of you must be

excited about meeting relatives, going places and

having fun.

However, you all must remember that a judicious

balance must be maintained between academics and

entertainment. To spend your time constructively you

all need to be organized and follow some regular

schedules as per choice. Your teachers have made

earnest efforts to design some constructive

assignments and projects to keep you productively

engaged during the vacations. Give some quality time

to your books and keep yourself gainfully occupied.

Have Fun Filled Holidays!

With Love
