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.

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.

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.
