__UNIT−1__

__Iterative patterns in shapes__

We see patterns in trees, rivers,
mountains, shells, clouds, leaves and more. Iteration is the repeated application
of a process. Here we are going to see how we use the shapes to form iterative
patterns.

__1.
Able to draw circles, spirals, ovals.__

In the earlier class you have
learnt to draw circles.

Circle, Spiral, Oval

**Activity**

Draw the above shapes and colour
it.

Using the above shapes we are
going to form iterative patterns.

**EXAMPLES**

**Activity**

**Required things: Paper, Pencil,
unused bottle cap, Cellotape.**

Take a sheet of paper, keep the
cellotape on it. Make two or three holes in the bottle cap. Keep the bottle cap
inside the cellotape and insert the pencil inside the hole, hold the cellotape
firmly. Draw the spirograph by dragging the pencil here and there inside the
cellotape. We will get the Spirograph.

**Teacher Note:** Teacher can elicit the student to use bangles
also instead of cellotape

**Try This**

Complete the
patterns using the given Shapes and shade with your own colour.

__2.
To differentiate and to compares the shapes drawn.__

Students, "Prepare your own
pattern of shapes using circles, spirals and ovals. Exchange it with your
friend and discuss".

__3.
To explore visual examples of repeating patterns__

**Do you know**

**Some visual examples are:**

Cactus is the example for oval
shaped pattern.

Shell of a Snail is the example
for spiral shaped pattern.

Bangle represents the Circle
shaped Pattern.

**Students see the visual examples
in the surroundings like**

Observe the patterns in the surroundings. Fill the rangoli with colours using your creativity. Use petals of flowers and fallen leaves from the trees to fill the Rangoli. Children prepare your circles, ovals and spirals from the chart (or) colour paper (or) with threads. Colour the prepared patterns with the same.
