 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 (45 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. 

 

 Review Questions (10 minutes): 

 Fill in the Blanks 

 

 A composite number has at least ___ factors. 

 The smallest composite number is ___. 

  ___ is the only even prime number and not a composite number. 

 

 Follow up Tasks (5 minutes): 

 Home work 

 Application Question: Think of a real-life example where knowing about composite numbers might help (e.g., arranging desks, dividing chocolates). Write 2-3 sentences about it.
