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.
