Learners 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. Learners play the factor game using a computer where they must find factors of a number.
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.
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.
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.
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.
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.
Young scholars simplify fractions using the TI-73 calculator. In this fractions lesson, students manually simplify fractions in their calculators by choosing the factor by which to reduce them. Using the given fractions, young scholars list the prime factors, GCF, and simplified answer.
