• What do you see in the picture?
• Spot things in the picture that look the same from the left and right side.

Teacher’s Note: Discuss with children about any local mela they have visited. Encourage them to look at the picture and observe different patterns, like tiling on the floor and the symmetry they see in objects and shapes.

Soni and Avi reach a stall where a man and a woman are making malas with beads.

2. On the previous page, tick the malas that are symmetrical.
3. How many such malas can be made? Discuss.
a. Tick the malas that are symmetrical and cross  the one(s) that are not symmetrical.

b. Now, use 6 beads of one colour and 2 beads of another colour to make symmetrical malas.

Teacher’s Note: Encourage children to see the differences between symmetrical and non- symmetrical objects around them. Provide them opportunities to share their justification and reasons.

Vanakkam! Rangolis all around!

Follow the steps:
rangoli

Let us Think


1. Observe the rangolis given below. Are all rangolis symmetrical?

2. Trace these rangolis on a paper. Fold the tracing paper in such a way that one half of the rangoli lies exactly on the other half.
equalhalf
3. Draw lines in the given rangolis that divide them into two identical halves.
4. Look for other symmetrical things around you. Discuss.

Teacher’s Note: Discuss about kolam, and the tradition and the States it belongs to. You can use the dot grid given on page number 192. They may use it for making symmetrical rangolis.

Teacher’s Note: Give additional exercises to complete the half of a given rangoli. Observe and discuss the ways children draw the other half of the rangoli. What do they notice while completing the other half? What strategies do they use? Ask children to collect rangoli patterns from different parts of the country and share them in the class.

Make Masks!

Teacher’s Note: Discuss with children why Avi was able to see only with one eye. Children should understand that objects that are divided into two exact halves such that one half superimposes onto the other half are symmetrical.

Tit for Tat
