Cube: ____________ $\quad$ Cuboid: _____________

Cone: _____________ $\quad$ Cylinder: _____________

What shape is between the red cuboid and yellow cuboid?

What shape is on the top of the orange cylinder?

What shape is under the pink cone?

Collect objects to make a house. Name the shapes and talk about their faces and edges. Which are straight and which are curved? Also describe how the shapes have been arranged. What part of the shapes can you see from a distance?

Devika went to a shop and bought a toy engine. Here is Devika’s toy engine. It has many parts. Count and fill.

#### Let us Discuss

Here are some more toys from the toy shop. They are made up of different shapes.

What shapes are used in these toys?

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.

#### Lets 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.

**Example**

The cylinder is on top of the cuboid. The cone is on top of the cylinder.

**2.** Look at these shapes and answer the following
questions
