Grading/ Notas
Sometimes for telling my Spanish students I'll grade their papers I'll just say Recibirán notas
If I wanted to say that I graded past tense, like I just finished grading their papers, what sounds better:
Les di notas/ calificaciones
or
Les puse notas a Uds.
or...???

I would like to add to what Dela Sierra has said.
"Acabo de revisiar sus papeles/tareas" I have just finished grading your papers/assignments
"He revisado sus papeles/tareas. I have graded your papers/assignments.
"Revisé" sus papeles/tareas. I graded your papers/assignments.
"Las calificaciones/notas son buenas/malas" The grades are good/bad.

"
"Revisar" was taught to me by a friend to be used as "to grade" though I know it isn't the literal translation.
This is just what sounds better to me, but I can't vouch for it being the more proper usage:
Past-perfect
He revisado los papeles de ustedes
Preterite
Revisé la tarea
