Adding & Subtracting Fractions:

I have been working with my students on adding and subtracting fractions so I thought I would share some strategies and resources!

Example 1: If the denominators are the same, add or subtract the numerators and keep the denominator the same.  Simplify if needed.

Example 2: If the denominators are not the same, find the least common multiple. Then use the least common multiple to find equivalents with denominators the same.   Next, add the numerators and simplify if needed.
