Factors and Prime Factorization
In this factors and prime factorization worksheet, 6th graders use examples to find all the factors for six numbers, then write six more numbers as products of prime factorization.
In this prime factor worksheet, students write numbers as a product of primes. Explanations and examples are provided prior to the exercise. This two-page worksheet contains ten problems.
In this prime factorization instructional activity, learners prime factorize ten given numbers. The numbers range from 6 to 25.
In this prime factorization activity, learners use skills to find the prime factorization of the given numbers. An answer sheet is included.
Monomial Greatest Common Factor
Sal explains that the greatest common factor of any number is the largest number divisible into both monomials and not necessarily the number with greatest value. He breaks down two numbers into their prime factors as a product of its primes then identifies the GCF of greatest common factor.
Common Divisibility Examples
Equipped with several examples from the attached module and from standardized tests, Sal takes viewers through the process of prime factorization and divisibility. He demonstrates each skill several times with many different numbers, allowing them to see each step in his work.
Comparing Fractions 2
Sal compares two fractions containing uncommon denominators. He analyzes both fractions using prime factorization. Note: This video could be confusing for struggling learners or those new to the concept. It would be best used for independent students with a strong number sense.
Identify Desired Results
Fifth graders use prime factoration and the use of prime and composite numbers.
Student Exploration: Factor Trees
Students explore the concept of factoring numbers. In this factoring lesson, students use factor trees to find the factors of different numbers. Students also discover what a prime number is and the term prime factorization.
Factors and Fractions
Sixth graders explore factors and fractions. In this factors and functions lesson, 6th graders explore prime numbers, prime factorization, and divisibility rules so that are able to work with fractions. Students also practice solving problems that their instructors model.
What Are You - Prime or Composite
Students explore the concept of prime factorization. In this prime factorization lesson, students participate in an activity where they find the prime factorization and greatest common factor of a number derived from their name. Students play the factor game using a computer where they must find factors of a number.
Construction Square Fun
Middle schoolers identify numbers as prime or composite and complete prime factorization of composite numbers.
In this finding factors worksheet, students practice finding all the factors of 24 in twenty word equations and then find the prime factorization in ten equations.
Factoring Composite Numbers
Ninth graders work with composite numbers to find their prime factorizations. In this Algebra I lesson, 9th graders use factor trees and division to find the prime factors of a number. Students explore the use of prime factors to determine the GCF and LCM. TI-nspire handheld required.
Factors Galore A: Common Factors
Students simplify fractions using the TI-73 calculator. For this fractions lesson, students manually simplify fractions in their calculators by choosing the factor by which to reduce them. Using the given fractions, students list the prime factors, GCF, and simplified answer.
Ninth graders factor equations and find prime numbers. In this algebra lesson, 9th graders find the factors and prime factors of a number using multiples and relatively prime numbers.
Prime Factorization- Reteach 9.2
Here is a prime factorization worksheet which invites learners to complete factor trees and use exponents when possible to write the prime factorization. They solve nine problems.
Chapter 2 Review: Prime Factorization
In this prime factorization worksheet, learners find the prime factorization of numbers by using a factor tree. They compare fractions and identify equivalent fractions, and find the greatest common factor, order numbers, and convert fractions to decimals. This two-page worksheet contains 18 problems. Answers are provided on the last page.
Leveled Problem Solving: Prime Factorization
In this prime factorization activity, students solve a set of 6 problems related to prime factorization, including determining whether numbers are prime or composite and determining factors.
In this prime factors worksheet, students solve 20 problems in which the prime factors of a one or two digit number are listed. Students tell if the number is prime. There is no instruction on how to find prime factors.
