Toy Joy

Some children are making animal and bird faces on old boxes, cans and paper.

Look at my bottle (cylinder). I made a puppy face on it. It has wide ears.

I made a pig face on the box (cube). It has narrow eyes.

I made a bird face on the cone. Look at its pointed beak!

I made a cat face on the cuboid. It has long whiskers.

Let us Do

Use old boxes (cubes and cuboids) and bottles (cylinders) to do craft work. Draw faces on them.

What did you draw on their faces?

Ch23

Jaya made some houses using different shapes.

Try to build such houses, towers, rockets, etc. using different shapes available around you.

Note that a cube is a special type of cuboid.

Let us Play

Construct and describe

Ask students to sit in groups of four or five. In each group one student selects any three shapes and puts them together. The student, then describes the sequence of construction and the other students have to build the same without seeing the original one. Let children take turns and play the game in the group.
