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.
