2 PREFACE Dear Hallmarkites Summer Vacation is a welcome break full of fun and frolic, long playing hours, picnics, exploring unseen places, spending time with family, developing new hobbies & interests and also staying safe and preventing summer brain drain. Let's make this vacation more interesting and meaningful. Here's an 'Activity Treasure Box' for you. When the school reopens, bring back your treasure. Your teachers will go through this with pleasure. Tips for a happy and fruitful vacation: Make a daily time table. Help your parents in house hold chores. Stay away from electronic gadgets as much as you can. Play outdoor games. Go for Nature walks with your parents as and when you can. Plant a sapling, water it and watch it grow. Read newspaper daily to keep yourself updated. Set aside time each day to enhance your vocabulary for effective communication. And don't ignore the tips given by Deedee. Hi! I am Deedee. CLASS-IX-2

3 ENGLISH TRAVELOGUE One of the best ways to immortalize your pleasure trip is through a travelogue. Sure, photos and videos are great for capturing special moments, but they don't tell the name of the Cafe you visited, how you felt at that moment - what the air smell liked, what emotions you had and the sounds that surrounded you or what was on your mind. So let's keep a travelogue this summer! Wherever you go for vacation (some tourist place, market, relatives or friend's house, etc.), keep entering all the things you do during your journey. To make it more attractive, you can embellish your travelogue with the photographs as well. Use A-4 sized sheets for your travelogue. AUTOBIOGRAPHY OF A TREE: Imagining yourself as a tree, write an Autobiography on the topic 'Tree The tree on the mountain takes whatever the weather brings' in your English notebook. BBC PRACTICE Do Page No. 5, 9, 11, 15, 19, 33, 51, 77, 82, 92, 208, 209, 236 in the BBC Compacta. SPELLATHON CONTEST Learn the spellings of all the difficult words from the chapters mentioned in the April-July months syllabus (refer the School Manoeuvre) of English, Hindi, Science and Social Science for the Spellathon Contest to be held post Summer Vacation. (July 15, 2018 tentatively) CLASS-IX-3
