Hi!

I grade homework on Khan Academy, but only take the highest grade. I allow students to complete the assignments as many times as needed, but note in the gradebook the number of attempts and time spent. 

Hi Eirene, Yes, I have used Algebra 1 for homework. I just give my students the score 3 out of 4 or whatever. However I let my students "fix" their scores up to a certain date.

Hello! 

I used it as a participation grade for homework each night and throughout the chapter.  I made them get to mastery in order for it to count.  

I used Khan Academy in Algebra 2 and would record the highest grade achieved for each assignment. I originally considered averaging several scores together and making one entry in the gradebook, but I opted to enter each score individually so students and parents could easily see missing or incomplete work. Hope this helps!
