First, let me say, I'm so grateful that Khan Academy is an option for learning. My kids have used it specifically to study math and programming. But we cannot find any math assessments at Khan Academy that would help us target learning. My 6th grader is ahead in math, but we're not sure exactly where and the issue of "too easy" v "too hard" is currently a barrier for her motivation to use the site. I hope KA will develop assessments soon. It could be as simple as asking a question or two before each section, and if they get it right, asking if they want to see the instructional video and practice or skip.
