PRAGATI PUBLIC SCHOOL

HOLIDAYHOMEWORK

2015-2016

CLASS :XI

Holidays are always awelcome breakfrom the normal routine and we all look forward to them. It gives us the opportunity to pursue all those activities that we enjoy but never found enough time to indulge in. So encourage yourself to take up a hobby, a sport or learn an instrument in these vacations. Urge yourself to read as “Books are our Best Friends”. Take membership of a library so that youlearns to enjoy the company of good books.

Another important aspect of a child’s overall development is directly related to the values that he/she embodies. No education can be complete without inculcating values. In today’s materialistic world value system seems to have been relegated to the background. Therefore, we would like to encourage you to spend time with your grand parents/ relatives during these holidays to bring clarity on moral andethical values

Holiday homework has been designed in such a way that the studentswillget a chance to inculcate reading habit as well as engage themselves in meaningful pursuits that will enhance their comprehension and reasoning skills along with honing their aesthetic sense.

We wish you a very happy and a fruitful family time during this vacation.
