Dear Parents
Greetings!

As summer season is at its peak, it's time to get away from the sweltering heat
and the dreary weather. So, while you enjoy your Summer Break in the cool
environs of your home, we have certain holiday tasks that will help you not only
understand and revise the concepts done in the class but will also help you be
creative and imaginative.

Our endeavour is to ensure the kids work on their own and come up with
innovative and creative ideas.

Here are a few tips to make the vacation a fruitful time for your child:

 Encourage your child to take up yoga or any other form of activity during
the vacation.
 Help your child to keep a record of the memorable moments spent during
the vacation.
 Encourage them to plant saplings.
 Take nature walks with your child as per your convenience.
 Set progress goals for the coming Term.

Have a special summer break!

(Open Minds)
