Adding and Subtracting Fractions

Topics for Today:

Today we began working on operations with fractions by adding and subtracting.   

The MAIN IDEA when combining fractions is the pieces of the whole must be the same shape and size to be able to add or subtract (need a common denominator).  We used the skills we built in the last unit to find the least common denominator (which is the least common multiple of the numbers that appear in the denominators of our fractions.
