What happened to the math knowledge map ? I can't find it?

I am wondering the same thing.  The grade based breakdown is useful for certain situations but the knowledge map was truly about education and not just schooling.

I work with older students with learning differences and many gaps. When you send them back to practice "2nd grade" level math they feel humiliated. When you use the tree, it shows what they are good at and where they need work from an individualized and wholistic perspective rather than by arbitrary grade divisions. Please, please, PLEASE bring back the knowledge tree. You can still have the skills also broken down by grade level. This was one of the things that Khan Academy did so well. Even as an adult, I would come look at the tree and practice to extend my skills. But I am not interested in slogging through all of the grade level lists to see what I still don't know. Really curious as to who decided this should be gotten rid of. It was one of your best resources. I am sad.

As another adult learner preparing to resume my math education after taking my last math class almost 10 years ago, I've got to agree with this. I don't want to study everything from pre-algebra to calc 2 all over again; I know there are some things I remember and some things I don't... The tree was a great way to figure out what was most relevant to the topic at hand; and it did a great job of showing how math topics build upon each other.

The tree was, to me, the thing that separated Khan Academy from all other similar platforms. And it's saddening that it's gone.
