Patterns in shapes
Creating patterns of regular and irregular shapes by stamping.
Example : block patterns created using handprints and foot prints are shown below.
Create patterns by impressing the following on a paper.
(i) Using dry leaves /fallen leaves.
(ii) Fingers, hands, toes, feet.
(iii) Using bangles.
Create patterns on your own by impressing the following on a chart paper and decorate your class room.
iii. bottle lids
My own patterns
Pattern in geometrical shapes
There are two types of patterns.
* Growing patterns.
* Repeated patterns.
a. Growing Patterns
If some patterns and designs increase or grow with straight lines and geometrical forms, they are called growing patterns.
Create some growing patterns using circle and square.
a. Continue the growing patterns.
b. Continue the growing pattern.
b. Repeated Patterns
If some patterns and designs repeat with straight lines and geometrical shapes, they are called repeated patterns.
Continue the repeating patterns upto 3 steps in the space provided.
Complete the buntings by following the pattern.
Do yourself: Draw some repeated patterns of your own.
Patterns are created by combining colours and shapes in different ways.
1. Match the following and complete the pattern.
2. Match the following.
Symmetries in shapes and patterns.
Do your self
1. Take a piece of paper.
2. Spill few drops of ink on the paper.
3. Now fold the paper and press it.
4. You will get a symmetric figure.
Symmetry means that one shape becomes exactly like another when you move it in the some way: turn, flip or slide.
Let us do
1. Take a sheet of paper and fold it.
2. Draw any shape at the folded edge of the sheet.
3. Cut the shape
4. Unfold it
line of symmetry
Note that one half of the shape is exactly like the other half. The line which divides the figure into two exact halves is called the line of symmetry.
The following letters are non symmetric and does not have line of symmetry.
F G J L N P Q R S Z
Make the paper cut outs of the shapes shown below with the help of your elders and keep them in in front of a mirror and observe the image formed in the mirror. You could see the other half of the image.
If a shape can be folded or divided into half so that the two halves match exactly then such a shape is called a symmetric shapes.
Example : 1
Example : 2
Line of Symmetry, Folding Line, Mirror Line, Mirror Line
Collect some symmetrical images from newspapers and magazines and Paste them to make an album.
Complete the symmetrical image
Teacher’s note : Teacher can guide the children to collect the symmetrical images in day−today life.
a. Draw the lines of symmetry for the following figures.
b. Circle the non−symmetrical shapes.
Draw the other half from the line of symmetry to make it symmetrical.
Line symmetry is also found in some letters of the alphabet. Complete, Write the letters with line symmetry.
