Joe Bower, a 6th grade teacher in Canada, shares the email and response from Alfie Kohn he sent in 2006 describing how he grades without grades.  In the comments at the bottom, many others share their approaches and struggles.

• Always convert all grades and numbers to a system of 100. It will not only be easier for you to figure out overall grades, but it will simplify your explanations to parents and administrators if they can see your grades in terms of percents.
• FAILING GRADES BELOW "50" ALWAYS GET MARKED AS A SCORE OF "50"
• All letter grades are converted to a numerical equivalent, equi-spaced from each other, based on a 100 point system. Then they are averaged as you would with other grades. Here is a chart you can use:

A++ = 100 (perfect paper with extra-credit)
A+ = 98
A = 95
A- = 92
B+ = 88
B = 85
B- = 82
C+ = 78
C = 75
C- = 72
D+ = 68
D = 65
D- = 62
F = 55

• EXAMPLE:

The student in the example received: 25, 80, 40, 95, 90. Average = 66%, Grade = D
The student's grades should be converted to 50 , 80, 50 , 95, 90. Average = 73%, Grade = C, which is a better representation of grades of A, A-, B-, F, F.
