Definition

What is it?

When we compare two or more things, 'smaller' means the one that has less size, volume, or extent. It refers to an object or quantity that is not as large as another when measured in some way.

Simple Example

Quick Example

Imagine you have two cricket balls. One is a regular cricket ball, and the other is a tennis ball. The tennis ball is smaller than the cricket ball because it takes up less space.

Worked Example

Step-by-Step

Let's compare the size of two tiffin boxes.

Step 1: Look at Tiffin Box A. It measures 10 cm long, 8 cm wide, and 5 cm high.

---

Step 2: Look at Tiffin Box B. It measures 8 cm long, 6 cm wide, and 4 cm high.

---

Step 3: To compare their overall size (volume), we can multiply length x width x height for each.

---

Step 4: For Tiffin Box A: 10 cm * 8 cm * 5 cm = 400 cubic cm.

---

Step 5: For Tiffin Box B: 8 cm * 6 cm * 4 cm = 192 cubic cm.

---

Step 6: Compare the calculated volumes: 192 cubic cm is less than 400 cubic cm.

---

Answer: Tiffin Box B is smaller than Tiffin Box A.

Why It Matters

Understanding 'smaller' is fundamental to comparing quantities and sizes, which is key in everyday life and many subjects. Engineers use it to design parts, architects to plan room sizes, and even doctors to measure growth. It helps us make smart choices, from buying groceries to building homes.

Common Mistakes

MISTAKE: Thinking 'smaller' only means shorter in height. | CORRECTION: 'Smaller' means less in any dimension – height, width, depth, or overall volume/area.

MISTAKE: Confusing 'smaller' with 'lighter'. | CORRECTION: Something can be smaller in size but heavier (like a small iron ball) or larger in size but lighter (like a big balloon). Size and weight are different properties.

MISTAKE: Not having a reference point when saying something is 'smaller'. | CORRECTION: Always compare it to something. For example, say 'This apple is smaller than that watermelon,' not just 'This apple is smaller.'

Practice Questions

Try It Yourself

QUESTION: A 1-rupee coin and a 5-rupee coin are on the table. Which coin is smaller in diameter? | ANSWER: The 1-rupee coin is generally smaller in diameter.

QUESTION: Your school playground is 100 meters long and 50 meters wide. A small park nearby is 80 meters long and 40 meters wide. Which area is smaller? Show your working. | ANSWER: School Playground Area = 100 * 50 = 5000 sq meters. Park Area = 80 * 40 = 3200 sq meters. The park area is smaller.

QUESTION: You have two water bottles. Bottle A holds 750 ml of water. Bottle B holds 1 liter of water. Which bottle is smaller in terms of capacity? (Hint: 1 liter = 1000 ml) | ANSWER: Bottle A holds 750 ml, and Bottle B holds 1000 ml. Since 750 ml is less than 1000 ml, Bottle A is smaller in capacity.

Real World Connection

In the Real World

When you buy clothes online, you often check the size chart to see if a 'Small' or 'Medium' fits you. Comparing 'smaller' or 'larger' sizes helps you pick the right fit. Similarly, when you choose a mobile phone, you might look for a model that is physically smaller to fit comfortably in your hand or pocket.
