The document describes children playing a game where they try to make circles on the ground in different ways: 1) Ariba first tries drawing a circle with a stick but her friends say it does not look like a circle. 2) Chippu and Naina then both try making circles on the ground. 3) Ariba then uses a rope with nails on the ends to make a circle on the ground with a friend. The children are able to make different sized circles depending on the length of the rope. 4) The document encourages using a compass to make better circles and explore different designs. It describes how a compass works to draw a circle.

8 Carts & Wheels

Hey! See, how big


this wheel is! I have
never seen a wheel
like this.

You must have seen many such round things around you.
List some more in your notebook.

Making a Circle
Naina, Chippu and Ariba want to play a game. They want to make
a big circle on the ground. But they cannot make it by tracing. So,
Ariba tries to draw a circle with a stick.

Chippu and Naina — It does not


look like a circle at all.
Ariba — OK! Why don't both of
you try?
Chippu and Naina both make
circles on the ground.

❊ Is any of these a good drawing of a circle? Discuss.


❊ Can you draw a circle on the floor with a chalk? Try.
❊ Also draw a circle in your notebook using a pencil.
❊ Look at the circles drawn by your friends. Who has drawn the
best circle?
The purpose of this exercise is to give opportunities to each child to make freehand circles.
They can also make circles on the ground with a stick. They can compare different drawings
to get an intuitive sense of the shape of a circle.

Making a Circle with a Rope
Ariba decided to use nails and a thread to make a circle on the
ground. She took a thin rope and tied nails on both ends of the
rope. Then she made a circle with the help of her friend. Look at
the picture and see how they are making the circle.

Can you also make a


circle with a rope and
nails like Ariba?

❊ Do the activity in small groups. Each group should take a rope


of a different length. See the circles made by different groups.
❊ Which group made the smallest circle? ___________
How long was their rope? ___________
❊ Does a longer rope make a bigger circle? ___________
Why is it so?

The length of Radius


rope used is equal
to the length of
the radius of the
circle.

❊ What was the radius of the smallest circle? ______________


The purpose of this exercise is to help children make different circles, measure the lengths of
their radii and see how the size of a circle changes with its radius.

Using a Compass
❊ Have you seen a compass before? How
will you use this to make a circle?
— Open your compass.
— Press the tip of the compass on the
paper. Hold the compass from the top.
— Without moving the tip, try to move
the pencil around.
— Do you get a circle?

Look for a mark where you had kept the tip of the compass.

This mark is the centre of your circle.

❊ Is this circle better than the one you made earlier without a
compass? Draw the radius of this circle and measure it.
❊ Now you can make your own designs like Daljeet had made.
How many did you make?

Guess how this design has been made. Use a compass to make a
similar one in the box.

Encourage children to explore their own designs with a compass. This will also give them
more practice in drawing circles with a compass.

Is It a Circle?

Naina was making a circle.

Ravi asked her for an eraser. She kept


her compass and gave him the eraser.
Then she started again to complete her
circle. But she got this.

Guess

j Why did Naina get such a drawing? Discuss.

Can a circle have more than one centre?

Another day Naina was using a compass to


make circle. But it came out like this.

j Did any one of you ever get a shape like Naina's?

Oh! The screw of the


compass is loose... Let me
tighten it... Now my
compass will not slip...
