Solvy looks to be a real interesting site to keep an eye on when it debuts. It is designed to help educators and students solve real world Math problems. For example, if a student wanted to be an architect or see how things were built, this would be a great tool. Also, this is a great tool w/ educational portal that allows educators to select what topics they want to cover while Solvy automatically grades their work. This allows educators to assess and differentiate instruction for each student.
I highly recommend checking out Solvy by clicking here!!!
