carol,
Interesting. Do you have words associated with the numbers? For example, is a 4 "Exemplary" and a 1 "Poor" or something like that? It helps me use words associated with the numbers and I think it helps students too. I typically use something like "Exceeds Expectations" - "Meets Expectations" - "Needs Improvement" and "Does Not Meet Expectations." Some instructors use terms like "Excellent, Needs Improvement and Poor" or "Demonstrates Mastery, Somewhat Mastery, Lacks Mastery." You have to work with the words that you need and ones that make sense for you and your students. Hope this is helpful.
