Diksha wanted to go to a big city
during her summer holidays.
Her father took her to Delhi
and they visited many old and
new interesting monuments like
the India Gate, Qutub Minar,
Safdarjung Tomb, Akshardham,
the National Museum, Jantar
Mantar and Sansad Bhawan.
Now she is trying to make a model
of India Gate using her wooden
blocks.

1. What parts of the building have you shown in your model
(for example, roof, pillars, base, etc.)?
2. Why did you select these parts?
3. What shapes will model these parts well?______________
4. How is your model similar to the picture of the real building?
__________________
5. How is it different from the real building? ______________
Discussion: What would happen if you removed one piece of your model?
• Would the model still look like the original building?
• In what ways could you make the model even better?

Do you think it looks like the Qutub Minar?...................
What shape would you use if you made a model of the Qutub
Minar? Why?...............…………………………….
How many such shapes will you use? ............................
Do you know: The Qutub Minar is
a World Heritage site and the tallest
building made up of bricks. It has 5
storeys and 379 stairs.
Encourage learners to observe a
street carefully and make a model
showing the main buildings on
the street.
Earlier, people made buildings with clay bricks, stone blocks
or wood. Today we also use concrete blocks, hollow blocks, etc.
What is common to all of these bricks? ………..
I have made something. Look
at my Qutub Minar.
Project Work
Note for Teachers: Ask learners to collect different boxes, bottles, cans, coconut
shells, etc., to model the given buildings.
