I am a middle school math teacher and have been using Khan Academy with my students since the start of the school year.
I have a couple of questions about Course Mastery Placement and Progress. Specifically, I want to know exactly how the Pre Algebra course mastery works. I assigned Pre Algebra as a goal last semester for one of my classes, but when I go to the Placement tab it only shows 6th grade and 7th grade as course mastery goals. I assume this means the Pre Algebra course is made of parts from both those grades, but I want to be sure.
Also, I am hoping to have students work on the same course this semester. Can I edit the goals from last semester and change the due date? Will it save their progress and allow them to continue working from where they ended up in December?
