These are the report card comments that I use in Grade 1 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).
They are 14 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).
(It has been pointed out that there is only 1 strand of science comments, this is because at my school, we teach the Structures and Mechanisms strand independently and the Needs of Living Things, and Daily and Seasonal Changes integrated in our daily calendar routine so we don't comment on them in the report card).
