My school uses JUMP Math and I fold it into a Kathie-Nunley-style Layered Curriculum Unit. This is the first Number Sense Unit, covering multiplication and division (I usually start there because pre-testing usually shows most of the kids are fine with addition and subtraction so I skip those lessons, remediating where necessary). I use "Level 2, 3, and 4" instead of "C", "B", and "A" because our school uses Ontario's level-based marks instead of letter grades. The download file is in MSWord for
