1. Identifies and uses prime and composite numbers
Understanding prime and composite numbers is a foundational concept in number theory. These classifications help students develop number sense and prepare them for work with factors, multiples, division, and more advanced topics like prime factorization.
A prime number is a whole number greater than one that has exactly two factors: one and itself. This means it can only be divided evenly by 1 and itself, with no remainder. Prime numbers are considered the building blocks of all whole numbers because every whole number greater than 1 can be expressed as a product of prime numbers.
Examples of prime numbers include 2, 3, 5, 7, 11, 13, 17, 19, and 23. These numbers cannot be divided evenly by any other whole numbers besides 1 and themselves.
