Numerator
Denominator
Represent this fraction as a pictorial model and on a number line.
Name 3 equivalent fractions to 1/2 and 2/3.

Turn and Talk:
1. How can you prove fractions are equivalent?
2. Why do we have to multiply or divide both parts of a fraction by the same number? (& what do we call it)
Abbreviated LCM
Need to know your multiples (facts)
Looking for common numbers among the facts.
Find 2 common multiples for 4 and 6.

What is their LCM?
Step 1: Find a common denominator by finding the LCM of the original denominators.
Step 2: Find equivalent fractions using the LCM as the new denominator
Step 3: Compare the numerators of the equivalent fractions (now that the denominators are the same)
Practice Time

2/3 3/4
Find the LCM of 3 and 4.
