Initiate discussion about the similarities in the shape of various musical instruments and talk about locally available instruments and the way they are played. For example, drum and tabla are played by beating them, whereas guitar and sitar are played using their strings, and shehnai, flute, etc., are played by blowing air into them.

Match the musical instruments and objects with their solid shapes. One has been done for you.

Heena and Atif

I want to decorate this gift box for my friend’s birthday. I have got ribbons, stars and pompom balls. Let us decorate this. We will place one star on each face of the box. Wow! It looks nice. Let me count how many stars we need. It has 6 faces so we need 6 stars. It looks really nice. Let me put ribbons on its sides.  Yes! Then, we need 12 ribbons for each side or edge. Some will be short and some will be long.
Let the children experience the surfaces, edges and corners of solid objects like chalk box, duster, chalk, etc.
Ah! Can we put these balls on the corners?  These colourful balls are looking good on all the 8 corners.

If you also have to decorate the following shapes in the same way with stars, ribbon stripes and pompom balls, how many of these items will you need?

Object Number of stars for the faces Number of ribbon stripes for the edges/sides Number of pompom balls for the corners

Touch and Tell. Who am I?

Collect different objects with variation in faces, corners and edges. Blindfold the child and ask them to pick an object as per the details given by other children. For example, a child may be asked to take out an object with one corner. Similarly, continue with other objects.

Project Work

Take a cardboard sheet and try to make an object with four faces. Now, try to make an object with one face.

Encourage children to discuss and find out the objects which have one, two, three or no corners. They may make such objects using clay or dough.
