Throw it away.
Imagine the limitations of the piece of paper shown above do not influence how you share the record of learning your students have done, with their parents, and the wider community.
Now remember the history of grading, which started with one William Farish (in Western culture – Chinese culture has been apparently giving grades to students for many centuries for the purpose of sorting their children into social classes.). William Farish (re)invented grades as a way to increase the number of students he could "teach’ for the purposes of lining his pockets (at the time, more students meant more money).
What would you do differently to share your student’s evidence of learning, if the limitations of the paper above did not exist, and if your purpose was neither to sort students into social classes or line your pockets by being able to teach more students?
