1 Holiday Homework Class X It is not enough to be compassionate. You must act. Dalai Lama Your summer holidays are around the corner and it is time for fun and frolic. But along with all this we must work on ourselves by understanding our social obligations. Incorporate the following into your everyday life during the holidays: a. Helping your parents Help your parents this summer in grocery shopping, preparing breakfast for them, cleaning the house and any other aid that your parents may need. b. Switching gender roles If you are a girl, learn to step into the stereotyped role of a boy by learning to change a tyre, change a light bulb, etc. If you are a boy, learn to step into the stereotyped role of girl by learning to prepare meals, clean the house, clean the dishes, etc. c. Social Service Give a thought for people around you who do not lead privileged lives. Contact an NGO, an old age home, an orphanage, etc and offer your service for at least 10 hours. General Instructions: 1. Collect evidence in the form of photographs, videos and certification for all the above mentioned work. 2. The above mentioned work is voluntary. However, being involved in it will help you to become a better person and a finer citizen. Task 1: Project on Money & Credit Money, says the proverb, makes money. When you have a little, it is often easy to get more. The great difficulty is to get that little. Adam Smith Content coverage: Case study on the operations of a Bank in your vicinity. Learning objective: Students will analyse the different ways through which a Bank is the formal repository of money and the source of credit. Execution of task: Plan a visit to a Bank of your choice. Research and Prepare a Case study based on the following guidelines: In your Case study highlight the following: TAGORE INTERNATIONAL SCHOOL EAST OF KAILASH, NEW DELHI Introduction to how a Bank functions. People who help us in a Bank. How is your money safe in a Bank? Role of RBI as a monitoring authority. Types of banking documents. How do you open a Bank Account?
