Opus: Add Rational Numbers

Teachers are always looking for good quality problems. They spend hours searching the internet looking for a problem that will not only align to the Common Core standards, but will also challenge their students. Opus does just this. On this site teachers can select the Common Core standard they desire and that will bring up a long list of problems tied to that standard. Teachers can select the problems they want and add them to their cart. When done choosing problem, teachers simply create a worksheet with their problems along with an answer key to those problems.
