Fraction Butterfly Anchor Chart - cross multiply to find equivalent fractions to compare fractions or add & subtract fractions with different denominators. A visual reminder of the strategy for adding & subtracting fractions found in the CCSS 5.NF.A.1 (a/b + c/d = (ad + bc)/bd). See http://www.corestandards.org/Math/Content/5/NF/A/1/. This is not intended to be taught on its own, but can serve as a reminder after the concepts that explain why this works have been taught.

My 7th grade math teacher had this exact sign when she taught us. I can never solve these equations without seeing it in my head...even 8 years later!
