11
ANNOUNCEMENT Tomorrow we are going to have our first “real” graded assignment over Least Common Denominator (LCD) and Equivalent Fractions.
12
Journal Time Pass out Journals
13
JOURNAL TIME Paste LCD and Equivalent Fractions papers into your journal.
14
A great way to remember NUMERATORS AND DENOMINATORS!
Numerator = Never under Denominator = Down Numerator denominator
15
LCD Find the LCD of 2 and Which numbers are the denominators?

You may be wondering… Why is it important to find the a common denominator?
46
Three Reasons 1. To compare fractions 2. To add fractions
3. To subtract fractions
47
TO COMPARE FRACTIONS Pretend you came home from school one day and your mom had two pans of brownies cooling on the counter.
48
TO COMPARE FRACTIONS You asked your mom if you could have some brownies.
49
TO COMPARE FRACTIONS Your mom said, “You can have a fraction of one of the pans of brownies.”
50
You can have: 6 of this pan of this pan OR
