MBIMS 07: Factors and Multiples

Course Summary

Learn factors and multiples of numbers in depth and how to apply them.

Course Description

In this course, the student will learn to identify factors of numbers to 144, leading us to define prime and composite. The student will use two strategies each to determine the Greatest Common Factor (GCF) and the Least Common Multiple (LCM) of sets of numbers. We will also address real-world situations where finding this information would be useful. #7 in Mrs. Becker's Intermediate Math Series (Followed by "Converting Fractions") Mrs. Becker's Intermediate Math Series is designed for math students in approximately 5th through 6th grade. Each class consists of a lesson including visuals and problems to work through together and independently.

Syllabus

1. Define factor and multiple. Learn divisibility rules for 2, 5, or 10. Determine whether given numbers are divisible by these factors. Define prime and composite. 2. Review definitions of prime and composite. Learn divisibility rules for 3, 6, and 9. Determine whether given numbers are divisible by these factors. 3. Define Greatest Common Factor (GCF). List all factors of given numbers. Identify GCF with this method. 4. Review definitions of prime and composite. Perform prime factorization using the tree method. 5. Use the tree method to determine GCF. Understand real-world application. 6. Review definition of multiple. Define Least Common Multiple (LCM). List multiples of numbers. Identify LCM with this method. 7. Use the tree method to determine LCM. Understand real-world application. 8. Mixed review
