What is Prime Factorization? • Check out the following links to learn about prime factorization: • Prime factorization is the expression of a positive integer as a product of prime numbers. • Prime factors and more • A Wikipedia explanation
Grade Level and Objectives • This lesson is intended for the middle grades or an early algebra course. • Objective 1: Students will be able to factor a number by creating a factor tree. • Objective 2: Students will be able to use proper exponential notation when writing the prime factorization of a number.
Factor Tree • Learn about what a factor tree is and how to create one for prime factorization: • A definition • An excellent PowerPoint on how to create factor trees. • Try a factor tree problem here! • A Prime Factorization Machine. • Try your own factor tree on this slateboard.
Divisibility Rules • Divisibility rules help when finding the prime factorization of a number. • Knowing divisibility rules greatly increases the speed at which a prime factorization if found. • The following links share the rules: • Rules for dividing by numbers 3-13 • Rules and examples
Exponential Notation • Exponential notation –A way to show repeated multiplication of the same factor • Repeated factors are displayed by using an exponent: The Prime Factorization of 12 = 22 x 3 • Check out this links for another example: • Exponential notation (near the bottom of page)
