</div>### Introduction Activity (30 minutes)

**Guess My Number (15 minutes )**

"Guess My Number" is a math-related game where one person thinks of a number between 1 and 100 and gives hints about its properties, such as "My number is odd" or "It's a multiple of 3." Students take turns guessing the number, and after each guess, they receive a hint, like "Too high" or "You're getting closer." The game continues until someone correctly guesses the number.

promoting critical thinking, problem-solving, and mathematical reasoning in a fun and engaging way.

**Composite Number:- Define ( 15 minutes )**

A composite number is a natural number greater than 1 that has more than two factors. This means it can be divided evenly by numbers other than 1 and itself.

**For example:**

4 is composite because its factors are 1, 2, and 4.

6 is composite because its factors are 1, 2, 3, and 6.

In contrast, a prime number has only two factors: 1 and itself (e.g., 2, 3, 5, 7).

### Main Activity (55 minutes) 

**Composite Quest ( 45 minutes )**

Each child receives a card with the numbers 1 to 100 written on it. They are then instructed to circle the composite numbers. The first child to complete the task wins.

2. The smallest composite number is \_\_\_.
3. \_\_\_ is the only even prime number and not a composite number.

### Follow up Tasks(5 minutes)

**Home work**

Application Question
