Question About Grading

Mila is in a school that still needs grades to be based on 100 points. In CI we all use rubrics now, of course, usually based on 5 or 1o points – certainly not 100. So most of us who are still in schools like Mila’s have to transfer an average of, for example, 7.4 of 10 over the course of a semester to a 100 point scale.
Now it certainly can’t be converted directly because 7.4 in a CI class is pretty good (esp. if we use the ISR right…) but 74 in a school that is still doing the 100 point scale can be labeled as low as a D. So what to do?
I remember having a conversion scale where a 7.4 converted to an 83 or something like that. There is actually a post here on this topic but it is  from long ago and is now lost amidst the thousands of posts here. But that is what I did when I worked in such schools, anyway – I just made a conversion chart.
Like a 9.0 avg. would be a 94, a 6.0 would be something like 76, etc. But then once a kid got that grade I literally changed it up or down to the grade I wanted, felt was right. Tina has called this grading from the heart. Doing that is easily criticized in our mechanical and robotic world, but I did it anyway.
Here is Mila’s question. We’re hoping for some good insights from the group:
“I have to grade my kids from 0-100. I asked them (French 1) to describe a character of their choice in French. I used the rubric from your latest book. Just words would have been great but they all used sentences which is awesome. Then I asked them 10 questions (because I need to grade them to 100) and one girl didn’t get one question at all…should I give her a 90? I hate to have to grade them to 100 but I gotta do it…”.
