Rival 5 is so much fun, that children and adults alike will forget that they are learning. I have been an educator for almost 30 years, and I know a great learning tool when I see one!  It’s a great supplement to textbooks, and great for students who struggle with learning math.  In addition, Rival 5 is a great game to play at home with family and friends.  Players will spend hours competing while learning and reinforcing mathematic skills.
