Your child comes home from school and on their paper is a single number: 9. Should you punish or reward them? Call the teacher? Call a tutor?
The answer is pretty obvious: we don’t know. A single number doesn’t really make any sense without having some context. Was it 9 out of 10 or 9 out of 100? Was it a score for points or a score from a rubric? We need more information to know what the number actually means.
The next questions for the teacher and the student are “How does this impact grading?” and “What do the numbers even mean when it comes to the grade?” Again, a number with no context doesn’t mean much. But in order to create meaning from this number, we need to start with what the number actually means once it is turned into a grade.
