Welcome to my math blog! The purpose of this blog is to help you stay informed about our learning and experiences that have taken place during our math class. I have also included links your child (and you) may want to use in order to supplement math learning in 5th grade.

### Adding and Subtracting Fractions with Unlike Denominators (continued)

Today was a continuation from our learning yesterday.  We practiced adding and subtracting fractions by:

• finding the LCD (least common denominator)
• creating equivalent fractions
• performing the operation (addition or subtraction)
• evaluating our answer to determine if it is in simplest form
• simplifying any fraction not in simplest form by using our GCF (greatest common factor)
To practice, we used a sheet I found in Teacher's Helper from The Mailbox.  It was in the Oct/Nov 2011 magazine,  The page was titled, "One Clever Cat."  I have linked the video (One Clever Cat) showing the first four problems as examples.
