Leveraging Learning

I have a problem and it is math. Common Core standards indicate that, as a proficient student, I should be able to explain the problem and look for entry points into it's solution. The problem is a loud one and I have heard it from students, from parents and from colleagues. The problem comes daily in the form of questions. "Can we do division today?"  "Can you send home some math problems so that my son can practice operations with fractions?" "How can we teach math in a project based, inquiry driven setting?" While I am not certain that I have entirely explained the problem - even to myself - I do believe that the more I grapple with the problem, the more clear it becomes. Solving the problem has become somewhat of an obsession. My first entry point was the Internet. Extensive searches did not yield the results I had hoped. I was able to see curricula from all over the nation & from all types of schools, but I didn't feel much close
