This should serve as a review for all concepts covered in Grade 6 math (according to the Ontario curriculum). You could use the review as a comprehensive year end review. Or you could break it up into parts (a midpoint review and a year end review). It's separated by strands. For Grade 5 teachers, this could be used too, by making slight alterations. For Grade 7 teachers, you could use this as a beginning of the year pre-test.
