I don't look at them as "grades" anymore. It has everything to do with how the child is doing in terms of common core standards but nothing to do with how the child is actually doing on a daily basis on assignments, tests, homework, class work. The only grading system that has any meaning to me is the one where I get rewarded for the work ... on the spot. There is no motivation for me (and my child) in doing my best job, completing 100% correctly and still only get 3 on a 4 point grading scale.
