These are the report card comments that I use in Grade 5 in Ontario, Canada. They are based on the Ontario Curriculum and cover all topics I taught and commented on (including Bible as I teach in a Christian school). It also includes general comments for a "homeroom" or "general" comment box with comments about use of time, organization, neatness, etc.
They are 17 pages of comments, broken into high, medium and low skill level.
This package includes a PDF (font protected) and a word doc (for you to edit, font and formatting may shift slightly).
