The emphasis of these files is for the student to find the least common multiple and/or the least common denominator to begin the process of adding rational fractions.
Included in this zip folder are 4 Power Point files. 1 is a student reference and 3 are assignments. A brief description of each:
The Student reference is a 1 page printable. It contains information on:
1. Finding the LCM of numbers by prime factorization.
2. Finding the LCM of monomials by prime factorization and expansion.
3. Finding the LCM of binomials and monomials at the same time. Expansion is used to describe this difficult concept.
4. Finding the LCD of denominators with monomials and binomials.
Assignment #1 is a 24 question short answer assignment. The student is asked to find the most occurrence of primes given prime factorization. The student is further asked to identify the LCM based on prime factorization. It is on 1 page for easy printing.
Assignment #2 is a 24 question short answer and multiple choice assignment. The emphasis is finding the LCM (and LCD's) of numbers and monomials by prime factorization and expansion. It is on 1 page for easy printing.
Assignment #3 is a 24 question short answer and multiple choice assignment. The emphasis is using expansion and prime factorization to transition from finding the LCM (and LCD's) of just monomials to including binomials. It is on one page for easy printing.
