Whether you’re studying for an upcoming exam or strengthening your concepts, our engaging animated videos, practice questions and notes offer you the best of integrated learning with interesting explanations and examples.

We may find shapes everywhere: in books, on toys, on walls, and even in the natural world. Students learn about the wonderful world of 2D and 3D shapes in the Class 2 Math book’s Chapter 2: “Shapes Around Us.” This chapter makes learning fun and useful by helping students recognize, categorize, and connect shapes to actual objects.

We’ll explore the main ideas from this chapter, covering 2D shapes, their characteristics, instances from everyday life, 3D shapes, faces, edges, and vertices, as well as how to recognize shapes with 1, 2, and 3 corners. Now let’s get started!

## What Are 2D Shapes Around Us?

Figures that are 2D shapes, or flat shapes around us, only have length and width and lack height. These forms cannot be understood like solid things; instead, they rest flat on paper. Common 2D shapes around us are as follows:

**Circle****Square****Rectangle****Triangle**

## Properties of 2D Shapes

Understanding the **properties** of these shapes helps children recognize and categorize them. Let’s look at the properties of the most common 2D shapes around us:

**Circle**:

- No sides, no corners.
- Perfectly round.
- Example: Coins, wheels.

**Square**:

- 4 equal sides.
- 4 corners (right angles).
- Example: Chessboard, carrom board.

**Rectangle**:

- 4 sides; opposite sides are equal.
- 4 corners (right angles).
- Example: Door, notebook.

**Triangle**:

- 3 sides, 3 corners.
- Sides can be equal or unequal.
- Example: Sandwich, traffic sign.

## Real-Life Objects Similar to 2D Shapes Around Us

There are shapes around us everywhere, and showing children how to identify them makes it simpler for them to see how math relates to everyday life. Here are a few examples:

**Circle**: Clock, pizza, coin.**Square**: Cushion, photo frame.**Rectangle**: Television screen, table.**Triangle**: Party hat, mountain peak.

This exercise teaches children to **observe** the world around them and develop **spatial awareness**.

## Introduction to 3D Shapes Around Us (Solid Shapes)

Solid shapes, or three-dimensional objects, have three dimensions: height, breadth, and length. Unlike flat 2D shapes, these shapes around us are common in daily objects and can be handled. Among the principal 3D forms that students will study are:

**Cube****Cuboid****Sphere****Cylinder****Cone**

## Faces, Edges, and Vertices of 3D Shapes

Understanding the structure of 3D shapes around us involves recognizing their **faces, edges, and vertices**:

**Face**: A flat surface of the shape.**Edge**: The line where two faces meet.**Vertex**: A point where edges meet (corner).

Here’s a breakdown of common 3D shapes around us:

**Cube**:

- Faces: 6
- Edges: 12
- Vertices: 8
- Example: Dice, Rubik’s cube.

**Cuboid**:

- Faces: 6
- Edges: 12
- Vertices: 8
- Example: Brick, shoebox.

**Sphere**:

- Faces: 1 curved surface
- No edges, no vertices.
- Example: Football, orange.

**Cylinder**:

- Faces: 2 flat, 1 curved
- Edges: 2
- Vertices: None
- Example: Can, water bottle.

**Cone**:

- Faces: 1 flat, 1 curved
- Edges: 1
- Vertices: 1
- Example: Ice cream cone, party hat.

## Real-Life Examples of 3D Shapes

As per the chapter Shapes Around Us, Connecting 3D shapes to real-life objects makes learning more meaningful. Here are some familiar examples:

**Cube**: Dice, gift box, ice cube.**Cuboid**: Book, brick, refrigerator.**Sphere**: Basketball, marble, sun.**Cylinder**: Candle, water bottle, drum.**Cone**: Traffic cone, ice cream cone, party hat.

## Shapes with No Corners, 1 Corner, 2 Corners, and 3 Corners

This section encourages students to classify shapes based on the **number of corners (vertices)** they have:

**No Corners**:**Circle**: A circle has no corners.**Sphere**: A sphere also has no corners.- Examples: Wheel, orange.

**1 Corner**:**Cone**: A cone has 1 vertex (corner) at the tip.- Example: Ice cream cone, traffic cone.

**2 Corners**:- Objects with exactly 2 corners are rare, but students can explore
**curved surfaces**that meet at edges, such as the opening of a**cylinder**.

- Objects with exactly 2 corners are rare, but students can explore
**3 Corners**:**Triangle**: A triangle has 3 corners (vertices).- Example: Sandwich, hanger, yield sign.

This classification activity helps students understand the **differences between shapes** based on their structure.

## Activity: Shape Hunt Around Us

To make learning interactive, encourage students to participate in a **shape hunt**. Ask them to find objects at home, in the classroom, or outdoors that match the shapes they’ve learned. They can list their findings and classify them as **2D or 3D shapes**.

**Example:**

**2D Shape**: Door (Rectangle)**3D Shape**: Dice (Cube)

This activity builds children’s **observational skills** and reinforces their understanding of shapes in real-world contexts.

## Conclusion: Shapes Are Everywhere!

In conclusion, CBSE Class 2nd Math, Chapter 2 – “Shapes Around Us,” offers students an engaging opportunity to explore the world of geometry through real-life examples. This chapter helps students identify and understand both 2D and 3D shapes, enhancing their observational skills and spatial reasoning. By connecting mathematical concepts to objects they encounter daily, learners gain a deeper appreciation for the role shapes play in their surroundings.

The “Shapes Around Us” chapter in Class 2nd Math introduces key topics like faces, edges, and vertices, providing students with the tools to recognize and classify shapes. As students progress, they can apply this knowledge in activities like shape hunts, discovering the abundance of shapes around them in a fun and interactive way.

Ultimately, CBSE Class 2nd Math, Chapter 2 – “Shapes Around Us,” encourages students to view math as an essential part of their everyday lives. With iPrep’s learning resources, students can continue exploring the fascinating world of shapes in a way that’s both educational and enjoyable. Keep learning and identifying shapes around you!
