Brick Patterns for Jagriti School
This is the true story of Jagriti School in Murshidabad (West Bengal). When its building was being made, there was a plan to make brick patterns on the floor and walls. Jamaal, Kaalu and Piyaar were the masons for the brick work. They wanted to get new ideas for the school building. So they took their other friends to see the old tomb of Murshid Kuli Khan. (See photos.)
This building has a big floor with about two thousand beautiful brick patterns. These were made by masons long back – about three hundred years ago.
Look how the bricks are arranged in these five floor patterns.
Which floor pattern do you like the most?
Have you seen such patterns anywhere?
The masons came back excited. Jamal said –Ah! In those days they had made so many interesting brick patterns. We had forgotten these! Let us make some nice designs on the floor of this school. Each mason made a different brick pattern. The school is proud to have such a be4autiful building! Children play and sing on it an also make new patterns themselves.
- Which pattern is made in a circle?
- In which pattern can you show mirror halves? Draw a line.
- Now you draw some new floor patterns.
How to Draw a Brick?
These are two photos of the same brick.
In one photo we can see only one face of the brick. In the other we can see three faces. Circle the photo showing three faces.
- How many faces in all does a brick have?
- Is any face a square?
- Draw the smallest face of the brick.
- Which of these is a drawing of a brick? Mark a (✔).
- Which of these are the faces of a brick? Mark a (✔).
- Make a drawing of this box to show 3 of its faces.
- Can you make a drawing of a brick which shows 4 of its faces?
A Wall that will not Fall
One day Muniya and Zainab are playing with bricks and making their walls. Each makes a different wall.
Zainab says her wall will not fall easily. Masons too do not put bricks one on top of the other, as Muniya has done.
What do you think? Which wall will be stronger?
Look for walls where you can see different brick patterns.
Different Wall Patterns
- Here are photos of three kinds of brick walls. Can you see the difference in the way the bricks are placed?
- Now match the photo of each wall with the correct drawing below:
Looking Through a Brick 'Jaali' The masons who built Jagriti School had also made different 'jaali' patterns on the walls.
- How many different 'jaali' patterns can you see in these two photos?
This is drawing of another beautiful 'jaali'.
- Now colour some bricks red and make your own 'jaali' patterns in the wall drawn below.
Can you see the window (jharokha) in this photo of the school?
- Now draw some jharokha patterns on the wall here. You can shade it black.
This' jaali' is from a library building in Kerala.
See how the edge of the bricks is used to make a triangle in the wall.
