Session 34: Composite Numbers

Session Title

Composite Numbers

Objective
  1. Define composite numbers and differentiate them from prime numbers
  2. Identify composite numbers through factorization
  3. Develop problem-solving and collaboration skills

Concepts

A number that is divisible by a number other than 1 and the number itself, is called a composite number.

Material Required
  1. Chalk & Board
  2. Game Card

Methodology

Activity-based and Cognitive skill-based

Session Duration

 90 Minutes

Introduction Activity 

GAME TIME: 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 Topic/ Activity: 

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.
