LearnBop is a excellent site for educators looking to help their students in any area of Math. The way this works is through an educational portal where students solve "bops" or math problems aligned to Common Core Standards. If a student has trouble working through a problem an innovative interactive visual workflow is displayed that helps students learn how to solve the problem. Best of all an educator gets detailed reports of students programs and allows them to differentiate instruction.
